[FR] Page-level font & font size

### Description

I think a search function that searches through a single page or the entire workspace is necessary. Additionally, adding options to customize each page would be nice as well. For example, I would like to have some pages in different languages, and having the option to change the font and font size could be useful, along with some appearance options.

### Impact

I had a problem finding items on long pages with a lot of data, so a search function is needed. There is no support for non-English fonts; I would like to change Persian/Farsi fonts as well.
