material 3 expressive design

[sojudu]

Can you update design language to material 3 expressive design please

[harshad1]

I am very slowly moving towards material design

It will take a while. Lots of people use markor and we have to keep all users preferences in mind

My next big effort will be to make the app themeable so we can get a nice flat UI

See #2803

It's not a full theme. Just options for a flat appearance. But I think it's a start
