Custom css themes shouldn't be too difficult. Probably pass in a url parameter for the them you want and then handle it in the template. Night mode has been requested.

Describe the bug

After closing the tab switcher, the progress bar remains visible after finishing loading.

Expected behavior

The wikipedia api provides a section an id (1 upwards), it'd be nice if that would also be included.

Example: https://en.wikipedia.org/w/api.php?format=xml&action=parse&prop=sections&page=License

Use new presets

I recently installed Kiwix 2.1.1 (2.1.4) on macOS 10.15.5. I loaded a Wikipedia (and only one), all went well.

Closed Kiwix. Re-opened it. Nothing in the list. Opened that same Wikipedia, it now shows twice in the list.

Certainly not a show-stopper, but
