Download List not longer loading

[beastyrabbit]

I i think i killed to download list by adding to many items.

The download is still running but i can not access the Download page.
Also I'm not sure how to remove old items. So is my download list broken for ever?

I also could be because i added multiple of the same item.
Not sure. The "have i clicked the session" conformation could be better :)

Thank you for all the work :)

Restarting the Docker seems to fix it.
Also now i also can not find the Limit again.
I got the popup 2 time that i added to many to downloadlist.

But i think this is because i clicked to fast?
Was still added to the List.

Yes, probably thats the reason for the message. I'll look into it and try to improve the download section a bit.
Adding pagination should help reduce the unresponsivenes of the download page and confirmation / better response messages should give more information about starting the download.

When I find some spare time, Ill try to fix this :)
