Hello there!
First of all, many thanks for your work on this project. This is only to report a very minor issue. If you look at the Brite theme CSS files:
https://bootswatch.com/5/brite/bootstrap.css
https://bootswatch.com/5/brite/bootstrap.min.css
https://bootswatch.com/5/brite/bootstrap.rtl.css
https://bootswatch.com/5/brite/bootstrap.rtl.min.css
As you can see, in the above files the 5.3.5 version of the theme is referred, but, the current release is 5.3.6, and, all other themes files refer correctly to this latest version.
Maybe this is not a real issue and the Brite theme refer the version correctly to 5.3.5, but, I want to report this here, so if this is certainly a minor issue, you can fix it.
Thanks again for your work on this project!
