There’s a bug dating back to October that made Heliboard unusable for me, because it cuts off half of the keyboard in landscape. Looks like it just got fixed but hasn’t been rolled out yet. Meanwhile heliboard is just really bad about learning new words (tends to think capitalized words are a different word and adds them to the dictionary when you start a sentence with them, can’t seem to handle autocorrecting to a word with an apostrophe). I gave up on it and went back to Gboard and I don’t think I’m going back. Honestly I’m real frustrated with the state of android keyboards right now. Swiftkey used to be awesome but MS ruined it. Gboard is better than it used to be but it barely has an options for customizing it. I don’t know anything better.
Huh I never type in portrait if I can help it, my thumbs are way too big for it. Landscape any time I’m typing and even then I wish I could make the keyboard bigger without losing visibility to what I’m typing/replying to. I also don’t swipe type, have never really liked it.
