TY for the appreciation! I think the lock should stay in the second sidebar, as to not alter the order of things. Also because I hate when things are offset and I can't "mindlessly" move the mouse in a direction or corner due to something I gotta click being placed weirdly. But I'd like to hear the others' opinions, maybe make a poll on that forum?
The panel: I saw it once when using the program, couldn't tell you how to trigger that because I didn't mentally process that it was an icon in the toolbar. That would be a good solution, putting the stats there and leaving just the Copy to clipboard pop-up when you click on the file path.
(I had this reply written for quite a while, I wanted to add a small paragraphs about UI palettes but for now this is absolutely enough).
