@Aury88 i really like this, great starting point!
hummlbach's idea is also really good(thinking along the same lines as aury88).
In what way will becoming a foundation effect the day to day running of ubports and more specifically, is becoming a foundation mostly to do with funding and all that pertains?
Thanks. And well done to all involved.
When the Pinephone/Librem 5 phones are released. Will UBports consider them flagship-type models due to their openness and will development be focused on those devices? If so will this mean older models like the BQ E5 and E4.5 become unsupported?
Regarding Posteo, i'm not familiar with it nor the calendar so I'll let someone else reply to you.
Dash etc: You can download Ubutnu Touch Tweak Tool (UTTT) from the open store and mess around with all kinds of settings etc. with that app.
Anbox: Anbox is still being worked on although there are some more important issues being address first so Anbox is not the primary focus.
Roadmap: There was one but I think they felt it was giving false hope to people that saw it if the features on there were not implemented in time so it was removed, I think you will now only get a next OTA milestone.
Keyboard There are some settings in the system settings for keyboard but nothing about enlarging the space bar as far as I know.
