Nice, haven't had much time to test it but here are my first impressions.
Good
- Fast, feels much quicker than the previous client.
- More efficient use of the screen, looks better/cleaner too.
Nice to have
- I can't seem to get the widgets side by side on my phone, works on the tablet though. (both have the same resolution and I have a fairly large screen on the phone) It would be nice to have an option for side by side on a phone.
- Would be nice to be able to move from group to group by swiping left/right.
- Support for custom widgets would be great, but I don;t know how difficult this would be to implement.
Bad
Charging 10 euro for a Beta version will probably put a lot of people off testing for you, I see it as a donation for all of your work, but others might not see it that way.
Al in all a much better client than the old one, I usually avoided using the old client if I could. But I can see myself using this one more.
