This is not a bug, is only a proposal. I need to be able to rename files by double clicking slowly, as in windows. I use F2 but made that option missing and I find it easy to create. click + 2 seconds + click = auto invoke F2 (or rename option enable) OR click file-folder with focus = auto invoke F2 (or rename option enable) I comment on whether it is possible to add the option in the development. Thank you very much. (Sorry for my bad english.)
