I havent gotten too much time to play around just yet.
The top menus seem like they have utility for sure. I am curious if I can customize it with more than the system options, like a specified app.
I am not noticing too much different off the bat. Certainly I appreciate it has security fixes.
Regarding the Android app alerts- I did see some mentioning of a hack to get that working but it was only a thread I read once while researching AlienDalvik- I am sure you know more about this than I and likely tried it.
There's an applet for the alerts, but it's kind of hit-and-miss, working with some applications and not working with others. The solution was hoped to be found in the new webkit, which was supposed to include notification support and therefore making a native web app for ProtonMail would have been relatively easy. But that improvement is apparently not there, either.
I suspect there will soon be top menu enhancements on OpenRepos.
The community meeting on IRC last week was pretty cranky as developers learned the amount of stuff that was promised for SFOS 3 but that isn't there. Jolla's rep said that no one ever said it would be in 3.0 and that all this good stuff will roll out over the life of SFOS 3, which to me is a little slippery on the part of Jolla.
My impression so far is that it includes improvements suitable for, say, a 2.3 upgrade but not a 3.0. Maybe you see things under the hood that justify it, but I haven't. Features are still lacking -- VoLTE, VoIP (important to me out in the country, where the cell signal doesn't reach; had wifi calling on my Blackberry since forever, but it hasn't come to SFOS yet, which is annoying). As to security, they still apparently haven't fixed the Mozilla security issue that everyone else fixed a year ago. The changelog and known issues list are disappointing. And there's a whiff of them concentrating on enterprise rather than end users, which is worrisome.
