For my server maintenance. It was toooo hard to implement vt100 functions.
I wish it help engineers like me...
This app use JSch for ssh connection. No other OSS libraries. (ex: I don't use connect-bot.)
Less app-permissions and small memory size, but serious made.
This is rare app to pass "Test of cursor movements" of vttest command.
I wanted a screen filter with few app permissions. And I wanted to make it a little more useful and fun if app requires strong app permissions like "overlap screen".
...But I overdid it. I often use it as a timer with the music box. (...this is screen filter ;-)
