Description of the Issue

Caret moves to the previous or next line when moving left or right and reaching the start or the end of the lines. There's no easy way to change the behavior unless resorting to hacky methods.

Steps to Reproduce the Issue

Load or type some lines of text. Press left until reaching the start of a line, or right until reaching the end of a line. If there's any line before or after the current one the caret will wrap to the end of the previous line or the start of the next one. Open the settings menu and go to Preferences -> Editing. No option there.

Expected Behavior

Having a checkbox for this.

Actual Behavior
