Hi @unisuperbox,
Sorry, in previous post i've all mixed in a pile((

I meant that if possible, use KDE Frameworks, аor example: for the archiver to use karchive.

Or make a similar a public program interface. Core apps, perform the same function in the listed environments, why not use the same basis (and the UI for each one is different according to HIG).

But it probably works freedesktop.org, as well notifications, indicators, and more.

PS. Sorry for my very bad English(

Is it possible to better use kde frameworkworks for the basis of the environment?
To avoid having to create the same thing several times, thus increasing the probability of bugs ("shortcut dont works in non-english" still happens; i dont know for UBports)

In general, it would be best that UBports LXQt and KDE have a standard API for programs, such as: indicators, file manipulation, fonts, passwords, and more.

In order to create the program once and it worked equally in these Qt-based environments.
