I am using a lot of filters to move my emails to folders automatically. Most of these filters are generated by using the ""Nachrichten dieses Absenders immer verschieben" feature. But now I have hit the 250 filters limit, and I'm not nearly done with filter creation.
The way I see it, there are two possible solutions:
1. I need to be able to export all filters, whether they are created automatically, or by hand. Export all filters as Sieve filters, which, I guess, is the format they are saved as anyways.
Using the export, I can then use external tools to consolidate them into a single, or multiple sieve filters.
This of course means, that I need to be able to active/deactivate/delete multiple filters at once.
2. Have a function that is able to consolidate multiple filters into one. This could work by selecting multiple filters via a checkbox, and then having the system create a sieve filter, consolidating all single filters. The single filters would then be automatically deleted.

Right now I'm at the limit and it is just not feasable to do this consolidation entirely by hand.

As another solution, you could just remove the cap for filters.
