Well uhhh, kinda late, but the “original” openboard project hasn’t got an update in like, 12 months. There are forks, though.

Fork with glide typing - Haven’t received an update in 11 months https://github.com/erkserkserks/openboard

“New” fork: https://github.com/Helium314/openboard

OpenBoard, Florisboard, AnySoftKeyboard

THERE ARE ALTERNATIVES, PEOPLE!

Ah, that makes sense, thanks for clarifying.

use MiXplorer or ZArchiver, they are good.
MiXplorer (and it’s addons): Google Drive / Beta (mixplorer.com/beta) (or, if you want to support the developer; Google Play Store (includes addons))
ZArchiver: Google Play Store

edit: corrected the layout.

Ah, cool! Thanks for the info!
