I have been using filezilla for years, but it had not improved at all, and is pissing me off now.
Any suggestions ?
There are not really many alternatives for professional use (on Mac), except perhaps Cyberduck, but it has its disadvantages.
Sorry for windows, I meant to say
I had a bad experience some years ago with Cyberduck (in Windows), not reliable in uploading all files. Might have been fixed by now.
You could use
NppFTP, plugin for Notepad++, works also for normal file uploading (I mean not only files opened in editor). Not sure if it's an improvement over Filezilla though.
What do you want to see improved?
