Re: takes a long time to display dirs with many files
OK, I'll try to generate such directory to see if I'm able to reproduce the problem.
Before posting, please read how to report bug or request support effectively.
Bug reports without an attached log file are usually useless.
Can you suggest if it takes long time to load the directory from the server or if the delay is caused by some processing on local side (like sorting file list, drawing it, etc...)?
If the first is true, I can hardly do anything with it as SFTP protocol does not have filter feature itself.
General filter feature for file panel (after the complete list is loaded from the server) is an option of current user poll, you may add a vote.
