### 4/5 — Keyboard issues…

*2025-10-01*

Amazing app, been looking for something like this for some time. Only complaint so far is there is no keyboard hide button when using the transformer tool, so you can’t press the “next” button. This leaves you stuck at the first page of the transformer tool.

**Developer response:** Thanks for the review Nick! We’ll have an update for that out ASAP and update our review response to let you know. 

Thanks for the bug report!

EDIT:
This bug should now be fixed!
