Besides standard settings that you frequently use, CLion offers various advanced options that you can use to fine-tune the behavior of the specific product functionality.
Since the advanced settings consist of different sections, you can use the search field to quickly navigate to the section of interest or the needed option. You can also search for registry keys since some of the advanced options have associated registry keys.
Use this section to configure additional options for CMake projects.
Use legacy generator for CMake 3.20 and higher
For CMake version 3.20 and higher, CLion uses CMake file API with Ninja generator by default. If you set this checkbox, the default generator will be Makefiles, and CLion will switch to CMake File API only if you specify a custom generator.
For older versions, CMake File API is used for the case of custom generator only regardless of this option's state. The default generator is Makefiles.
Do not trigger CMake reload on external changes if auto-reload is disabled
Select this option to completely disable automatic reload of CMake projects including external changes. See Load/reload CMake.
Perform initial profile configuration when a project is opened for the first time
Clear this checkbox if you prefer CLion not to automatically configure and show a default CMake profile when you open a project for the first time.
Reload CMake profiles sequentially
Select this option if you want CLion to reload CMake profiles one after another. By default, CMake profiles are reloaded in parallel, but sometimes it may cause issues when reloading CMake. Use this option to resolve such issues.
Enable CMake Presets integration
If you clear this checkbox, the profiles will not be generated for presets, and the existing presets-based profiles will be deleted upon the next CMake reload or project reopening.
Use floating toolbar to notify that CMake project needs to be reloaded
By default, when you make changes in CMakeLists.txt, CLion shows a floating notification indicating that the project needs to be reloaded. You can disable the floating notification by clearing this checkbox.
For more information, refer to Reload CMake on changes in CMakeLists.txt.
Use this section to configure additional options for the Clangd engine.
Use Clang-based indexer
Set this checkbox to enable Cland indexer for Find Usages.
Keep obsolete ASTs in clangd
With this option enabled, obsolete ASTs are not deleted immediately, which helps speed up navigation.

Select to connect to the configured Docker daemon after CLion starts.
Image registry entities loading limit
For performance reasons, by default, CLion shows only the first 100 images in a Docker registry. Increase this number if you need to list more. This will also increase the memory usage.
The log tab should be the first tab for the docker container
Show the Log tab as the first tab in the container overview pane.
Apply :z mount option to almost any bind volume for SELinux systems
Use this section to configure additional options for working in the editor.
Don't copy/cut the current line when invoking the Copy or Cut action with no selection
This option lets you override the default behavior of copying Control+C or cutting Control+X the whole current line when nothing is selected in the editor.
Don't select the copied line after invoking the Copy action with no selection
By default, when you use Control+C without selecting anything, the whole line gets copied. With this action, you can avoid that selection.
When pasting a line copied with no selection
You can change the default Paste above the caret line behavior, and select either Paste at the caret line that restores the old Copy / Paste behavior or Trim if pasted middle line that will remove the unnecessary spaces before and after the copied line if it is pasted in the middle of the line.

Tab character rendering
You can select one of the following options:
Left margin in distraction free mode
This option lets you adjust the left editor margin in the distraction-free and zen viewing modes.
By default, the editor text in these viewing modes is centered vertically and the text column width corresponds to the Hard wrap at option on the Editor | Code Style page of the IDE settings Control+Alt+S. This means that if your code will be centered when formatted properly, but if there are long unwrapped lines, the text might go beyond the viewport while there is a large margin on the left. In such cases, you may want to decrease the left margin using this option.
Force soft wrap in documents with lines longer than
The default number is
Move caret down after Comment with Line Comment action
This option lets you configure whether to move the caret to the next line if you comment a line with a line comment Control+/. Note that if there is a selection in the editor, the caret will not move regardless of this option.

When this option is enabled, you can double-click tabs in split editor tab groups to change relative size of the tab group: the first double click will extend the tab and its group to the maximum and shrink all other groups to the minimum width/height; the second double click will allocate the same width and height for each tab group.
Alternatively, you can choose Find Action popup Control+Shift+A.from the main menu or pick these actions from the
This option can work together with Perform 'Hide All Tool Windows' / 'Restore Windows' with double-click on editor tab, but be prepared to have multiple changes in the IDE layout every time you double-click a fie tab.
Equalize proportions in nested splits
Use this option to even the size of multiple horizontal or vertical splits in the editor.
