While I'm all for more integration. I (PERSONALLY! Only myself. I'm happy for everyone that still uses TiCo!) am sad that it's for a mod that I won't be including in any of my packs simply because it's TOO good. I end up never using anything from any other mod ever, even if they're better, because the TiCo tools start out better, and I just get into the rut of using them.
Also until recently (I would assume I have Boni to thank for this reversal) the entire slime knights ecosystem stuck out like a sore thumb. It was the best alloyer for a very long time, but you couldn't extend it or anything... and steelworks kept disappearing of the face of the planet every time I wanted it. Which means new alloys may as well not have existed to it. Also those odd issues Reika was having with integration a while back, because... reasons that I'm not going to list 'cuz drama magnet.
I totally need a tool belt that lets me easily switch between like a half dozen tools of each type. Not my whole hotbar or expanded inventory, just basically a "mode" switch. So I can use my Terra Shatterer for AoE mining, and my Bedrock Pick for general mining, with a special pick for this one mod ore, maybe the old ExU destruction pick for when I don't want Cobble. Switch between an excavator and a silk touch shovel, have a precision and lumber axe... that kind of thing ya know? Not really a RoC/CrC suggestion, though I'd much prefer it in RoC to CrC... as RoC contributes to the problem, whereas CrC is less about tools and more about magic structures and personal power. More of a "Why haven't we seen this in a user-configurable (IN GAME) manner?" kind of thing.
