Besides standard settings that you frequently use, RubyMine 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 advanced options have associated registry keys.
Show only line bookmarks in popup
By default, RubyMine shows only line bookmarks in the bookmarks popup (Shift+F11 or Bookmarks.). Disable this option if you want to see other bookmarked items in the popup, for example, files or folders. For more information, see

The number of expressions to be saved in the Evaluate expression history.
Connect to Docker automatically at restart
Select to connect to the configured Docker daemon after RubyMine starts.
Image registry entities loading limit
For performance reasons, by default, RubyMine 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.

Show the Log tab as the first tab in the container overview pane.
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 Ctrl+C or cutting Ctrl+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 Ctrl+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 unnesessary spaces before and after the copied line if it is pasted in the middle of the line.

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 Ctrl+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
