[Duplicate] Questions about the new flow

I am using Swiftkey 6.5.3.35 on a Samsung S7 running Android 7.0.

First, I would like to say that I think that moving the focus to corrections instead of predictions was a mistake. I miss predictions, but I have been using the new version and trying to adapt, despite not really liking it. I have some questions.

1. How do i capitalize the next word? I'm flowing and my last flow was correct, and now I wish to capitalize the next word (say, a proper noun). If I hit shift, it capitalizes the last word. If I just tap or flow, then it's not capitalized. Example: "Yesterday I visited the State House."

2. Hitting spacebar after a *correct* flow inserts two spaces. How do I stop this? Autocorrect is set to off.

3. Punctuation is slightly messed up as well. If I insert punctuation (: ; / - + etc) after a *correct* flow, it auto-adds a space in between. It makes using colon, semi-colon, etc very awkward. It's there a way to fix this? e.g. "To whom it may concern:"

Thanks!
