I agree that the ionic popovers look a little bit heavy (well that’s entirely subjective) but I suppose you can fix that through styling (SASS/CSS). What I would want is something looking more like the familiar “tool tips”.
I just open and close them in my Controller, not in a service.
By the way what do you mean by non-interrupting? What I would like is to be able to close them by clicking outside the popover instead of having to click the button. Or optionally with a timeout where it auto-closes after some time.
Haven’t spent time on this but I suppose you can build this stuff yourself either based on ionic-popover or from scratch.
