Of course, although the same behavior is exhibited with every dark theme I've tried, even the native Windows high contrast themes.
I currently use After Dark CC Theme For 8.1
with minimal steps required to make it usable (I don't like installing .dll files for which I don't know what they do).
The bare minimum installation is as follows:
1) Install the supplied UXThemePatcher
(essential, without it there is no way to use custom themes on Windows :( )
2) Copy the content of the supplied Themes
folder into Windows/Resources/Themes
3) Right click on the desktop, Personalize
and select the After Dark CC Blue
I additionally use the supplied OldNewExplorer
tool to hide some of the less used UI elements which haven't been skinned properly like the ribbon.
Dark themes really make a difference for people which spend a lot of time working on a computer, especially late or over night, so it would be beneficial in my opinion to have at least some basic support for those in one (if not the) best FTP clients for Windows out there.
