Trying to get used to Gimp coming from Photoshop. Making progress, but one thing I can't deal with is having that yellow dotted line around selected layers. I know that I can turn them off in the View menu - but I have to do that for every new image. Is there a way to either completely disable the lines, or set a keyboard shortcut to toggle them off/on? Thanks
To permanently disable layer boundaries from the File > Preferences menu chose Image Windows > Apearance to untick Show layer boundary. This then works on all newly created layers.
To toggle visibility of layer boundaries create a keyboard shortcut from Edit > Preferences > Interface. Select Configure Keyboard Shortcut and scroll down to the entry Show layer boundary. By default this entry is disabled. After selecting you can assign a not yet otherwise used keyboard shortcut by simply pressing it.
