I saw this Reddit thread about a catalyst skip button and thought this would be a great addition to your fantastic QoL addon and many in the comments seem to agree 😂

Apparently the button the person was wondering about was from this addon Profession Shopping List

It would be very nice to have this option in Plumber as well when you are farming transmogs on alts, maybe it's also possible to add a instant skip button for vault loot too? 🤔

E: Added video to show how it works
Just a toggle setting that auto skips the dialog could work too instead of having a button for it on the frame

Surprised this doesn't have more votes or visibility. The added additional Tweak that Profession Shopping List had with the Instant Catalyze button was fantastic, and I can't seem to find a discussion as to why it was removed.

The dev moved the feature to his other addon and made it into a shift click function instead of an extra button on the UI

I am also surprised it's not already a feature of Plumber. :D

I very seldom need a 5-second "cooling down period" before catalyzing a piece of gear. By that point, I've already made up my mind. Like it has been said before, it's not such a big deal if you are catalyzing one or two pieces of gear every couple of weeks, but when you are farming old content and catalyzing multiple pieces back-to-back, the 5-second wait is irritating.

PS: To make an instant catalyze button macro, use the following: /run C_ItemInteraction.PerformItemInteraction()
