I'm looking forward many many years from now. I'll be selling my Braveheart edition to Pawn Stars

I really thought it will sell out in just days after launch. I wonder if only 3k were really sold for BraveHeart Edition.

I fully share the same sentiment as Marius in this blog. Based from what I read, people are expecting too much from the PinePhone. Librem 5 and such and some expectations are not practical. Many seem to want a phone that's very identical to their linux desktop/laptops. It looks and sounds cool but in real scenarios, they don't make much sense. That's why I think UT might not be a popular choice for many enthusiasts interested with the PinePhine. But regardless of this, I'm still hopeful the every linux OS out there will be successful in their own ways

All those issues were introduced in the Unity8/mir but most of them are being worked on if not already fixed
The keyboard showing in the external display has been closed just today I think.

So for now, you have to restart unity8/reboot after plugging in the external display for it work. Scaling is fine in the right side of the screen but if you want, you can set system scaling to 8 (1080p monitor) so that everything looks fine.

There are a couple of issues affecting external displays in devel but most of them are being worked on already. Good to know it works on you. Did you need to reboot/restart Unity8 for the external display to work? or it just worked?

So I think this issue isn't specific to the "back" function as I don't think it will ever come to UT or even make sense to have it. At the moment, all edges are already reserved for the system except the bottom edge. We maybe can start from that be we need something that is convergent. My implementation in Palitan/Pesbuk works great for me but having it in every app means that all other bottom edge gestures has to be removed i.e. Morph browser.
This is definitely a difficult issue to resolve although it's not really a very urgent one.

@makeixo The buttons in the header are still available for tapping or clicking but you can also swipe from the bottom to trigger those buttons depending on which side you swipe from. It's not a replacement per se but more of an alternate way of navigating especially useful for touchscreens and phones

I've used Qt Creator, Geany, and Kdevelop and they work fine with proper integration/configuration of clickable.

Yes, this is definitely something that UT needs to improve. So far different apps handle it differently but mostly using the bottom edge. Hopefully, someday we can come up with something that can be used globally but the big problem is that UT doesn't really have the "back" function like in Android/Windows mobile. So this can definitely be a hard issue to tackle.

Of course, I'll be promoting my apps
You can check out Palitan or Pesbuk in the store.I've implemented something that isn't specific to the "back" function but might be a viable solution for buttons at the top

@magdesign Are you on stable or devel?
I switched my daily drive from MX4 to Nexus 5 but so far it seems that I have a bit of battery drain and I'm not getting a good standby battery life unlike on MX4.
