Semicolon and other less common punctuation

I saw someone else half address this, but whenever I try to add a semicolon after using flow input I get a space been the last word and the punctuation. If I want to use a semicolon or make my own made-up-phrase, I either have to backspace the last letter of what I've swiped (flowed) so it knows to look at what comes next as individual characters, or use the arrow keys to back up after hitting that semicolon and backspace spaces. Same applies to hyphenated words or series of words, but there's no reason to have the semicolon/colon/hyphen or dash not but the end of the preceding word. Particularly with the semicolon. I tend to like my punctuation as a way to fragment what would be a run on sentence and other areas where it would be appropriate but SwiftKey wants there to be space on either side of the ";" character or when using hyphenations. It should always hug the word to the left like a comma would; this range is same idea applies to full-on commas as well: it wants to have a space on either side instead of jumping back to the end of the last word like typing a period would. Why not give some (slightly) more obscure punctuation and symbols the period and comma treatment where after flowing a word it auto-spaces, but if a period, comma, or second space is input next that keyboard will smartly insert the formatting and punctuation before the auto-space between words.

Another hiccup I have that's always a fight is, for example, I want to list a file extension, SwiftKey will fight me to the pain several times in a row to not have it try to reformat that section to a URL.

It's to the point that I will flow a word, [backspace], [backspace], retype last letter of word and then long-pressing the "n" key for my semicolon to be in the proper place.

Side note:if the keyboard has to autocorrect the second half of a hyphenated word or expression it will add a space between the hyphen and the word it fixed looking like "blahblib- blahblah", assuming it had to fix my 'blahblah' for me, when the goal was "blahblib-blahblah".

SwiftKey is still hands down the most robust, well-rounded keyboard and I want you guys to continue to dig in your heels, keep pushing the envelope, and retain that innovation and magic autocorrect advantage without it getting too bogged down and keep it first time user friendly!

Keep up the stellar work guys!

Also if you wanted to add gravy it'd be nice to have a way to flow on a larger screen (5.5" on my Pixel XL) when I'm manipulating the phone entirely with one hand without totally scrunching up the keyboard with the one-handed layout.
