So, I recently started provisioning with a new character and very quickly ended up with dozens if not 100+ recipes.
I quickly reached level 50 skill and now 90% of those recipes are irrelevant to me, but I have to slog through them any time I want to fulfill a common Writ or just make items for consumption for normal game play.
A full filtering search similar to 'Guild Store' searches would be nice.
However, at the very least there should be options to 'Show Only Recipes At My Level' and 'Show Only Recopies At My Provisioning Skill Level'.
Just those two filtering options would make managing recipes much easier for 90% of game play.
