Motivation

I've encountered several issues related to text editing:

• The 'Backspace' key occasionally malfunctions.
• The 'Superscript' and 'Subscript' functions aren't working.

Solution

• All markdown features working as expected.
• Additionally, I suggest considering a font change. The current handwritten-style font could be replaced with a simpler one, like Noto Sans, to enhance the app's appearance.

Saber version

• Device: LG gram & Galaxy Tab S7 FE
• OS: Windows 11 & Android 13
