Agree with everyone who requests Unicode version of Salamander.
Reason of that - not even because users want, but because mostly all serious file managers support Unicode (Total Commander, Far, Directory Opus and of course Windows Explorer, etc.).
But of course if someone wants to use cp1251 (cyrillic) names on system with cp1252 system CP settings or some symbols not limited to English language on Cyrillic system (I even don't say about some Asian symbols or some special symbols) - we'll be stuck. I need to rename French/Spanish named files on my system or use Windows Explorer to copy/open such files. And this is not about 1 file, but about hundreds in different folders, so Salamander stuck in copying this folders and that's bad - one symbol and you get error.
I'm software tester (seriously - real QA/QA lead

) and I even can provide free professional testing/bug-writing for Unicode support if it will be decision to make it high priority (I cannot test Salamander stable, because of high load with my actual work on project, so I want (if needed) support fully only Unicode support, because of my personal interest).
Another propositions (sorry if I double someone's request):
Allow unpack/archive operations to be performed on background + allow to add these operations to queue + use all CPU threads in case of multiple archive operations in a same time (if not queued)
Unified queue dialog for copy/move/archive actions (like TC, but improved - with slider to control speed, with ability to open full-size copy dialog for any item, etc)
FTP Client connections export/import (reg-file is ok, but maybe something encrypted will be good too)
Portable version of Salamander (natively portable or paf-platform, but official one)
Busy/locked file unlocker plugin (bundled).
Text-file viewer to have syntax highlighting (at least for some most popular file types - ini, htm(l), cmd, xml, c, cpp)
docx, xlsx support for viewing
...will think more
