Display Setting doesn't allow setting scale back
I'm running beta6 on Pinephone. The Setting>Display allows me to change the scale to 100% (I think it starts at 200%). That allows me to see all of some apps, such as Firefox and Thunderbird, which is great. However, the next is small, so for many apps, I would like to change the scale back. But, Setting>Display no longer shows that option. In both cases, the Resolution pulldown is there, but only when the scale is 200% are the options for scale shown.
As an aside, it would be great to have a toggle button for scale in the top-bar pop-down (that shows wifi, bluetooth, etc.). Is that something which I could work on? I haven't put together a developer environment on my Manjaro laptop yet, but I plan to.
Thank you for your time, work and help.
