Thanks for your suggestions.
The 3.0 release of RAW Power will be focused on brushing, ratings / tagging / flagging, queries, and support for Photos library on Mac.
That’s a lot of work, so I won’t be taking on keywords in that release. However, keywords are definitely on the near-term roadmap.
Some of the other ones may make it in 3.0 – not sure yet.
Keywords not showing in the info area: that’s a simple thing to add. I’ll make a note to put that in 3.0.
