Description

I have deployed AFFiNE locally but I noticed two issues when editing text:

1. There is no subscript/superscript functionality.
2. Only ' Find' is available but no 'Replace'.

These small but critical features are important for text editing and workflow and I am wondering if they can be added.

Thanks:)
