skillet can indeed make reagents that are craftable (it's an option you must enable, tho).
i'm not sure about the trunk version of skillet, but my branch (which i hope to fold into the main trunk) does queue up craftable reagents from other professions.
clicking the gear selects the recipe used to create the item, btw.
There is obviously something quite bugged in the Trunk version of skillet, then. That option is definitely there (checked by default), but clicking on it does nothing... adding it to the queue does add the reagents too, which is nice (I love how skillet uses a single queue and not a diff one for each prof like ATSW), however it doesn't get it right all the time. For example: on my BS/miner, I queued up a light skyforged axe just to test and it added 12 truesilver skeleton keys (quite a bit diff from mithril bars, lol). Dunno if this could be an incompatibility with other addons (such as Manufac), or fixed in the development version...
But, I know this isn't a forum on Skillet, so I will migrate this thread over there.
Thanks for your help guys
