Probably a 'blokey' thing - but I thought icons on desktops were a last century 'thing'
A single thread for 'feature requests' could soon become a multi thread, probably better to have a separate subforum - or have a convention in thread names - [Feature Request], [How do I ...], [Calibre Crash] etc.
Itimpi is correct in pointing out that there is a formal change request system, but some (many) enhancements are done as a result of issues raised in the forum. Presumably the developers raise the change request - Kovid even posts a link to code that implements the change to let the OP know.
