User interface
It definitely changed since siena. However it might be only me but it is kinda confusing. I used to do coding in advanced mode in siena but for some reason in powerapps it doesn't feel right. Perhaps it is because of fonts and sizes what are way too small and everything is hidden. I tried the top menu to do coding but that is totally unusable because it just takes too long to find something and some of the options seems not to be there (or I just can't find it). The dropdown with options is just ridiculous. I understand that you tried to make it more user friendly but I think you just made it more confusing. Once again why don't you bring the panel with option from Visual Studio here. It is easy fast and clear for everyone.
Gallery
I have noticed that you have added "WrapCount" what is huge advantage from siena. I have also noticed you have given us an option to hide scrollbar. However apart from that it looks exactly the same as in siena. (still a lot missing)
Buttons
You have round them up what looks much more better but I still haven't found an option to change button shape with picture. (fix me if I'm wrong)
Refresh DataSource
Finally some progress but I still haven't figured out how to do exactly what we can do with excel file also with collection collected within the app. Also I don't quite understand how can we do this if we would create an app for another person with different OneDrive credentials. Well but obviously this is not your target in "business access" and therefore it is quite unusable...
So thanks kindly for giving me access to your business powerapps. There is no point for me to try something else in this powerapps so if you want me to take the privilege then go ahead. I'll be more then happy to go back to powerapps on "personal access" with all issues sorted. Meanwhile I still think that this business access has absolutely no point at all.
Good luck!!
