I guess you would have gotten a much better experience 6 months later: and that's an unfortunate coincidence that your testing/review happened just few days before some of the major needs (Signal, KeePass) were released to the Openstore , and some of the issues you mentioned is just about to be addressed: like modern and stable web-browsing.
Anyway you will always be welcome to do an update or a new review in few month/years!
