After using FreeCommander and Nomad.net and NexusFile Manger before those for quite a few years here's a list of mostly minor stuff I've missed from my previous experiments.
1 - A "Refresh View" entry on right click menu when clicking both empty space or an item - Windows explorer and FreeCommander had it and it was quite convenient
2 - An option to choose priority between folder thumbnails/desktop.ini and/or custom icons in settings - I would very much like to use "Show folder thumbnails" on by default but can't because they override some of my special "main folders" I had setup with custom icons through desktop.ini
and lastly the only two "truly big" feature request that are unlikely to be "easy"
4 - An editable breadcrumb bar that can fully replace the address bar - Like Windows Explorer's Breadcrum. I believe I'it's been asked around several times before
5 - A nice graphical user interface based batch renaming function - Maybe like Advanced Renamer or FreeComander's
Maybe some of these are already possible or achievable through scripting and I am unaware of it. If so I'd be thankful if you point me in the right direction, I'd be delighted to know I could already do some of these.
