Dear ChimeraX team, I have a suggestion regarding the Tools side panel. Many users that I know struggle with the lack of vertical space in the side panel. I think a feasible fix would be to give users an option to have the side panel extend all the way to the top, with the top tool panel ending earlier (like in the mockup pic 2 vs pic 1). Chimera can already “trim” the top panel if the window is too small (pic 3), so I think it might be possible to implement my suggestion. You could increase the vertical space even more if you'd allow the bottom two bars (command line and the line that shows chain information) to also end where the side panel starts (also pic 2). Please let me know if I can help in any way. Many thanks, Filip Roch Imperial College London [image.png][file-26198a563e09e770990c3b3d083fc949 copy.png] [image.png]
