Readest

Hello. Today I'm requesting a portable version of what I consider to be the best software for reading ebooks.

I consider it so for several reasons:
1. It's free and open source.

2. It offers a (albeit minimal) cloud storage for syncing files, notes, and reading progress.

3. It can open multiple ebook formats, including the problematic fixed epub3 format that plagues more popular ebook readers.

4. It's cross-platform: macOS, Windows, Linux, Android, iOS, and the web.

5. It receives regular updates.

6. It works perfectly.

Therefore, I'm not asking for something that's of personal interest to me; it's something I consider important, even essential, for the vast majority of users.
