### 2/5 — Please fix the keyboard size

*2022-04-08*

Great app, super helpful. I just can’t use any elements starting with a letter that’s further right than i.

### 1/5 — Can’t get the full keyboard

*2021-02-08*

I wasn’t able to get the other letters like O for example

### 2/5 — Would of been good but ads were cancer

*2018-06-29*

Seriously too many ads
