Adjust font size for individual files & Quick font size adjustment in Android app

Use case or problem

When adjusting font size on PC or Android app, the fonts in all files are adjusted. I’d like to see Obsidian remember the font adjustment for each individual file.

Besides, another related issue, the quick font size adjustment in the Android app seems not working. I’d imagine when I use fingers to “zoom” the page, the font size gets changed, but currently the quick font size adjustment in Android app seems to have no effect.

Proposed solution

Make fonts size be adjusted for each file instead of globally. Enable quick font size adjustment in the Android app.

Current workaround (optional)

I have the same problem on my phone and on my tablet although the zoom-toggle is on in options. Please solve this problem.
