So, here's the thing.
I set up my necromancy revo with my additional bar with all my abilities for thresholds and ultimates, threads of fate, the scythe thing and so on. It fills up basically most of the bar for manual inputs. I believe the movement abilities surge/escape/dive is very important, so they go on the bar too. And of course, the wars retreat button, because panic happens.
And its also important for muscle memory and user enjoyment, its so nice to know in your head where a button is, no matter what boss you fight. It feels good. To make a unique loadouts for each boss isn't very enjoyable and frankly, very frustrating.
Even half a bar on display somewhere would be huge for me. To add a couple of loose ends. Or a quick swap button between 2 bars.
So are you saying that, google/apple don't allow you to update your UI? Because i couldn't find any reasons why they couldn't change their app UI after going live? Can you provide a link or something to this? It's my understanding that they cant have inconsistent UI per device. But that's different than user customization.
It's super inefficient! And that's why I'm asking for just a handful more options. Not all 5 additional bars that PC has.
Of course screen sizes differ, my laptop is a standard 15 inch screen, i adapt to RS3 with my limited real-estate, i have seen those 4k boys with their massively fancy sleek UI loadouts. This is no different. Some would use it, some wont. And i think people would be okay with that.
And yes, of course its doable, very much so. But is it fun? Not really. You cant even remove an ability from the bar in the powers screen once you've placed it. The only way i have found is to go out the settings window, unlock the bar, make it my active additional bar and drag them off...
