Can't the filtering be clientside theoretically tho?

[bastimeyer]

No.

Thanks alot for the replies, I understand now. Guess some multithreaded querying with multiple languages in parrallel wouldn't work either, I don't know enough about the API limitations.

Do you have plans for a new release, or should I rather build the current Version myself for now?

Also thank you very much for maintaining this project, it's a really nice tool <3

multithreaded querying with multiple languages in parrallel

Those massive API requests are not possible since Twitch is already rate limiting the new API (which btw is a total disaster) and has recently tried to also introduce it to the old one which is currently used here. They've backpedaled though after receiving a shitstorm on their forums. Still, filtering features and the likes can only be implemented here if they are supported on their API and doing multiple network requests to achieve just one goal is always bad. See my comment here regarding a recent temporary change on the followed streams API endpoint:

Do you have plans for a new release

Probably this weekend. I need to check a couple more things first, and I don't have the time today.

or should I rather build the current Version myself for now

You can always build from the master branch. The more people who are running the latest dev version, the better the chances for finding bugs/issues which I've missed.

it's a really nice tool

thanks
