QuickPath suggestions

I’m sick of all the errors that iOS INTRODUCES automatically to my QuickPath texts, emails, etc. Unless I carefully proof every sentence before tapping Send, I’m guaranteed to have at least one or more bizarre errors introduced. I’d like to see the following changes:

1. Allow us to edit a personal dictionary. This would eliminate most of the errors that the dictionary automatically creates, as well as ones that it’s learned from my occasional errors and by my failing to stop its incorrect substitutions.
2. Allow an Adult setting for the dictionary. I don’t need iOS to censor my language, forcing me to manually edit its autocorrections. I don’t want iOS to determine what’s allowable language or topics.
3. Reexamine the dictionary. There are words in it that aren’t actual words, while eliminating real ones. Try typing “pennies” and watch it automatically substitute “Pennie’s”—which, if an actual person’s name, would generally be spelled “Penny’s.” Considering I didn’t drag over a Y, this error is unacceptable. And it regularly substitutes Abes’s and abs for “and,” leading to a lot of unnecessary editing.
4. Consider grammar when making autocorrections. It’s hard to believe that this is impossible given the current state of computing.
5. When editing text, stop automatically selecting an entire word rather than just placing the text insertion point. In most cases, I do not want to remove or replace an entire word. Automatically selecting one interferes with editing and makes it more difficult to set the insertion point without inadvertently deleting text.
