[feature request] Mouse support

[derVedro]

First at all guys, you make a great job. I shed several tears of nostalgia when I started the editor for the first time. I like chr and I would like to see the mouse supported. May be this is the wrong place for and it's more a Tui Widgets "issue", but I just wanted to offer that thought - it would be amazing if mouse interaction could be implemented down the line. Keep up the incredible work!
