Once I have set up the workspace, I usually don't want to change the arrangement of the tool tabs.
When editing photos, I regularly move the tool tabs by mistake. I would like to have, for example, an option tick in the settings that locks the arrangement so that only opening and closing is possible.
100% agree that this option should be added. I was a little shocked to learn that this wasn't an option. I constantly move my tool tabs by mistake when editing.
