To be more specific, lets call it an idea from the perspective of a passionated user.
I just wanted to describe what i personally want from a mobile device. Since ubuntu touch is already based around the sidebar, one might think it could be well suited for this idea. But maybe i am the only one impressed by this.
I think i got the part with the top-left-os. That sounds not as easy as adding 2 lines of code.
Btw i planning to invest in a new device. On top of the list are the poco x3 pro for its screen refresh rate and the galaxy s10e for its size and build quality. For now it seems more convinient to choose the later for reaching over to the left side.
