P: Please add keyword auto-complete that offers suggestions from the existing keyword list

Yes, autocomplete metadata and tags with suggestions.

+1, even better, perhaps also have suggestions before you even start typing, and a way to see all the keywords. I hate ending up with "mountain goats," "mountain goat," "goat," and "goats" because I can't remember which keyword I've been using.

Yes please. Keyword Lists as well.

+1 Here!!!

yes please

I would agree - although there are a lot of additional keyword management elements I'd like to see, this would be a pretty simple first step.

Just wanted to bump this a little. I've been making a conscious effort to develop a workflow for my new pictures. With the lack of multiple flags in Cloud, I'm using a keyword to mark photos during my first quick flip through an import that have potential but will need specific attention to get there. Not having that keyword autocomplete is an annoyance.
