Does anyone know an Open Source split keyboard for #Android tablets?

Ideally I would love to have a fork of #hackerskeyboard, with a split layout so I can type without stretching my fingers.

@WingmanJD
Install #Termux and then its #vim package, pkg install vim
Preferably along with #HackersKeyboard

@redandgreen14@fosstodon.org I'd like to add some more recommendations:
- #conversations Great XMPP app with really good UX. Replaces services like whatsapp for me
- #BarcodeScanner for scanning QR Codes (e.g. for wifi profiles)
- #Termux basically a GNU/Linux system in a app - use it for remoting into my server from time to time
- #HackersKeyboard Keyboard with buttons like Esc (for Termux)
- #dsub #ampache client with offline cache

other stuff I use has been recommended by somebody else already
