Option to change font size

First of all, thank you for this amazing app. As a power user, I really appreciate how this bridges the gap for my Obsidian workflows.

To start off, it would be great if we could customize the font size in the editor. On tablets specifically, the fixed size can feel a bit off when using a keyboard or a pencil. Having a slider or a few presets in the settings would make it much more accessible and comfortable.
