This is actually not a request for a new feature, but a request to bring back something old. When you hit F2, the newest version of WinSCP doesn't highlight the entire filename anymore, but omits the extension. I understand that this might be useful for a certain type of user that deals with certain types of files on a Windows system. For me however (1) my server runs linux which means that a . doesn't necessary mark the file extension, and (2) I often use F2 so I can copy the filename and paste it somewhere else - for that, the new feature is pretty annoying.
Maybe, as a "best of both worlds" it's possible to make this feature optional for every user to decide? Thanks for considering!
