Swiftkey - How to handle Auto Capitalization with URL and Email Strings

I like a lot about Swiftkey. But after a few years of using it, some of the annoyances haven't been fixed and I haven't "eventually got used to" the nuances of it like I thought I might.

This one has me stumped.

Enabling auto-capitalization means typing out a web address, or email (anything with a period in it for that matter), adds spaces and capitalizations throughout the string. Trying to get it to type out correctly, while the fragmented string is also changed to auto-corrected words is unimaginably infuriating.

So I gave up and turned off auto capitalizations, lowering myself to texting like an imbecile, all in lower case (because who's got time to hit the shift key - am I right?).

Enter a second, supplementary, infuriating bug.

Swiftkey, when I can be bothered manually capitalizing, seems to think I want that text saved to the custom dictionary. So, for example, the text: Swiftkey drives me crazy. Absolutely throw my phone against the wall crazy. Will result in the wors Absolutely being saved to the dictionary. Next time I go to use absolutely in a sentence it comes in capitalized.

Enter a third, supplementary, infuriating bug.

Swiftkey has a neat feature where you can long press on a predicted word, and select do not predict again. Great, if it worked. Long pressing Absolutely and selecting this removes the word from the custom dictionary, completely. Except next time you go to type absolutely and type abbsolutely or some other fumble, it is not corrected to absolutely because that word is gone. Instead something else is dropped in absolute for example, or worse perhaps, your mistake goes in abbsolutely.

Ideally I'd rather use auto caps. And have some way to enter strings with periods better. But with it off there is an unacceptable series of bugs that I think need to be fixed.

Am I doing something wrong?
