A button to cancel the local feed extraction

[matt-from-wii-sports-2]

Describe your suggested feature

Completely fixes #6656, related to #6938

It would be nice to have a button near the progress bar to cancel the extraction. Only videos from the already processed channels would be added to the feed

Other details

After stopping the extraction, there should probably be a text warning at the top of the feed saying that the feed has not been fully updated. The warning should not be displayed when no channels have been processed, such as when starting the update and immediately pressing the cancel button

Alternatively, there could always be some text displaying the latest update time and encountered errors, I can create another issue for that

Sorry why we need to have a button to cancel local feed extraction?

It's not a critical feature, could even be marked as a low-priority one. However, it could be useful when having an unstable connection or switching networks, since it will allow for a quicker manual reload compared to reopening the app. It's also a good UX feature to be able to cancel an action, particularly a long-running one

There is no guaranteed order, in which channels are refreshed, so you would just end up randomly cancelling the refresh, resulting in worse efficiency then fully fetching all channels.

I think it would not be a huge problem. The goal is to get at least some updates when pressing the button and being able to easily toggle the refresh again. Even if that new, full refresh will update some channels that were already updated just some time before, that is the same behavior that there is now. It's just about the UX, not the efficiency

I personally agree with my pre-speakers, I don't think such a feature makes much sense. Usually users want to get a full feed update, and not only update half of it to cancel the process in the middle...

If you want to cancel the process for whatever reason, you still have the option to close the app completely which cancels any ongoing processes.
