I am pretty sure you can mass extract components already, when I right click on them it gives me the option (would be nice if hoof made the same adjustment to his code as yuzzan made to the helper code to work on the stashes)
As far as using up coding time to add more guild store slots it would be fine it it applied to more then 1 guild in the entire game... If there was more then 1 or a few that this applied to go for it, but an update that only affects 1 guild is wasting Hoof's time.
You guys are cleaver I think you could find a way to clean up the store and utilize 1500 slots
Adding discounted potion only slots to the store wouldn't necessarily only affect FFS. Depending on how discounted they were, others might be interested.
Can I interest you in some antique FF formerly useful elite sets?
