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)
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.)
You're in luck; this was implemented today with https://cgit.kde.org/dolphin.git/commit/?id=5454283008f26d377a6403861a3cdd7992dbbd38!

This is great news for me. Dolphin has an excellent usability and with this even more.
