SFTP mode need a lot improvements

ssh host > open embedded SFTP\SCP
- Select folder with files, at down menu Ctrl+A - only available options is download, no remove uvailable.
- Impossible to disselect files.
- F2 rename menu - can't close with Esc.
- Can't leave home (connection) directory.
- Edit\upload at not home (permissions) directory don't work. Nothing happens.

This mode looks like WinSCP, but can't replace any of it functions.
Literally only files download from home directory is working, but only if you are owner of them - never.
