Help needed with mlterm

[VoVaN]

I have been rxvt-uninode user for quite a while, but recently I've decided to move to mlterm. While rxvt eats memory like crazy, mlterm in the same situation uses 10 times less . It's always takes a while to make initial configuration, so the same story with mlterm. It works perfectly fine but I have a few questions regarding adjusting some configuration parameters, so below they are:
- Home/End keys and well as some Ctrl+Fx keys aren't working (I've tried to adjust termcap, but can't find the proper key codes)
- While pseudo graphic characters displayed properly it the plain terminal, they don't work as expected in tmux/screen
- How to make 265 colors working properly? I've adjusted the colors file, so it includes all the colorXXX=#XXXXXX lines and tried to use TERM with mlterm-256colors/xterm-256colors, but unsuccessfully...

I'd appreciate any help or links to the useful info about the
configuration questions above.
