I don’t know how to make that button look bigger in CSS, I use Windows and I think is weird because obsidian not have UI consistency for Windows, especially the button of titlebar (It looks fine though in OSX)
Unfortunately this implementation I posted a year ago breaks the titlebar on mobile. I’ve recently updated it on my own theme to not cause issues if my theme is used on mobile. My theme, CyberGlow, is the only one i know of that at this point in time changes the height of the titlebar, i’ve been trying to make it fit the Windows10/11 look to fit in better with the other apps…
you need to go into your vault → .obsidian folder → themes and create a new .CSS file if there isn’t one there. Alternatively you can start by using a theme you like using.
You can find community themes via Obsidian settings.
