FR: Global block/keep rules

[thiagowfx]

• [X] I have read this document: https://miniflux.app/opinionated.html#feature-request

As a follow-up of https://miniflux.app/docs/rules.html#filtering-rules:

Block rules ignore articles with a title that match the regex. Keep rules keeps only articles that matches the regex.

...one generalization is add block/keep rules globally.

Explanation

Currently one can only add block rules on a per-feed basis.

The idea here would be to add two new settings (/settings): global block rules and global keep rules (=affects all feeds).

• Articles from a feed foo whose title match the global block rule (OR possibly its own individual feed block rule) would be ignored.
• Articles from a feed foo whose title match the global keep rule (AND possibly its own individual feed keep rule) would be kept.

Practical usage

• Completely Ignore buzzwords / trends (you may not be interested in): For example, one could add a global block rule like (?i)web3|crypto|sponsor.
• Take a break from repetitive subjects (you're interested in, but maybe read too much about the topic): For example (?i)covid.

The use case for "global keep rule" may be limited, I don't have any myself. I am mostly interested in a "global block rule", but I think it could make sense to add "global keep rule" as well for consistency purposes.

I'd be willing to give it a try to implement this (although I am not familiar with the codebase as of today), but first I'd like to know whether it sounds like a feasible FR.

I support this request, I have missed this feature at least a few times this week as I often end up blocking the same keywords globally in my newsfeed, typically things related to topics I don't have interest forever or at this time. It would be nice to block those globally instead of having to repeat the same rules in all feeds (I have hundred RSS feeds :-) ). Thanks !
