I think can be useful to know what app develops think about their ubuntu touch app port/programming experiences...and I think collect these experiences could be useful to help other app and OS developers to make the right choice:
Return of Dr. Destructo based on Allegro Game Library

Hi guys! about this topic I didn't read any news about the collaboration between ubport and yunit team and I'm curious to know if it is already reality or a work in progress.
For what I understand yunit has successfully ported unity code on debian stable and is backporting to 16.04. will this migration to 16.04 be useful for ubport too?
is it still possible to merge all the fixes and update both projects had done on their branch?

Also I would like to know if there is some sort of collaboration between ubport (and yunit) with the canonical mir team

about the mir support by canonical this is the actual situation
Also mate team seems interested in a mir-based wayland compositor/client. is the collaboration between all those project on this common objective possible and already started?
I hope in some news in the next Community Update ;-)

bye guys and thank you!

+I need a way to start an app after choosing a content and not choose a content after starting an app. honestly when I work I hate the in-app gallery/library/playlist (though I find them useful when I explore my files when relaxing), also because my work is basically editing various typology of files organized by task and not by typology.
in a confined OS like UBport, in its future snap architecture, I really need a trusted app to easily choose and give an access/edit permission to an app non-owner of a specific file.

• all the stuffs, already said by others, regarding search-cut-paste-copy-link-rename-(un)zip files

I love it! really impressive job in both the desk and the smartphone visualization.
only few things (just to break the long chain of compliments):
in the smartphone mode I would prefer the initial upperbar stay visible even if I scroll down the page ( with the menu button on the left clicking on the ubports mascot but this is a plus) better if it is more thin with less vertical space consumption
in any case the links/menu should remain in any location. if I choose e.g. the device page I should find in that page a way to go to (e.g.) forum... better if this way is consistent on each page (maybe something like on the left maintain the project links menu and on the right a specific menu for the page, if it exists like in the forum page)
but one thing I really miss is a way to directly go from your website to the https://uappexplorer.com/
or to
https://open.uappexplorer.com/
A smartphone OS is nothing without its app ecosystem and considering that now you are the OS development center I think you should also be the focal point
even for app developers (wishing to )developing for your great OS

Again guys, thank you guys! ;-)

I agree with all your points.
I need a smartphone that is also a smart-assistant for my works and that keep (or try to keep) google or any other patriotact approved company away from my data.
Also a Phone that is easily hackable is a must to make my phone cover my needs and this is connected to another point in my wishlist: the phone should be useful for the open communities and the onlus. eg: On the "market" I should be able to directly donate money, see/contribute to the sourcecode and directly login and communicate with the community behind the develop of the apps or see their news/blog post. the smartphone should give an independent and easily way to keep communities in contact, share information/allert with their affiliates and interact with them. so, long story short, what really mater is an opensource SO, based on opensource services, with an easy and powerful sdk ;-)

@Flohack I 1000% agree with you. UT should have only opensource app and/or be based only on open source services by default....
neither Android is based on proprietary services/app by default (excluding google services obviously).
About the proprietary services/app the thing that we really need is a way to find easily them (for example why many user don't know about LoquiIM? it is probably hard to find)

Imho by default we need only the very basic things also for convenience reasons: the OS with the DE-GUI, with the hardware exposition to the user space and the ability to integrate the apps with the system(ie I install an app "clock-x" and "mail-y" and I want them be able to put an applet on the toppanel), the phone calls, the sms app, and a way to install anything else.

@Phil-UK about whatsapp support why not try LoquiIM?

imho there is already a good initial range of (proprietary) services support on UT but they are hard to find or not integrated in the smartphone.

sorry for the intrusion
@WebDrake about the Mir support by canonical I think anyway they would continue to support it but limited to the IoT systems..so probably there will be not PC graphic drivers port/support. imho the transition to wayland is necessary even if canonical will continue to support it..that support probably will not cover the pc market
