[Feature Request] Add fit to width on continuous mode also

[rainbowdrg]

Is your feature request related to a problem? Please describe.
I really like Mango because it support nested folder structure to manage mangas which other manga server/management tools doesn't support (tried Komga and Kavita but both not support this folder structure). For example, I can put 'To Love-Ru' and 'To Love-Ru Darkness' under same folder like below:

To Love-Ru -> 01           -> Vol 01
                              Vol 02...until End
           -> 02. Darkness -> Vol 01
                              Vol 02...until End

And I personally like to watch manga in webtoon or continuous mode. These are the reasons I choose Mango (not yet try Tanoshi, look like it support nested folder structures also but don't have continuous mode for reading)

Now, I'm facing issue that sometime the words may too small and hard to see for old comic which having left and right pages in 1 image.

Describe the solution you'd like
Add fit to width on continuous mode also

Describe a small use-case for this feature request
I'm know paged mode has fit to width feature but I personally more prefer to read/watch manga on continuous mode. Please add the same features on continuous mode also. And optionally, can add to choose side padding in percentage like Komga.

Additional context
Example of manga which have small words in continuous mode:

Choose Side padding in Komga (Optional, not so important for me but will use sometime)

Thanks
