Someone possibly as neurotic as me!!
I am constantly closing one tab somewhere at the beginning of the line of tabs and then having to close all the tabs to reorganize them again. (Drag and dropping tabs only works correctly if you only have 1 line of tabs.)
I would love to have a system where when the user clicks Once on the layout/sheet to the right, that layout/sheet opens. Just one click. I don't need the tabs at the top.
Of course that wouldn't work for games with a thousand layouts and hundreds of sheets, but for my projects, where I only have around 5 of each it would be amazing.
Of course, they're implementing much bigger features, so I'll just live with the tabs.
