> BUG 2: every time you use --resume, your entire conversation cache rebuilds from scratch. one resume on a large conversation costs $0.15 that should cost near zero.

I use it with an api key, so I can use /cost. When I did a resume, it showed the cost from what I thought was first go. I don't think it's clear what the difference is between api key and subscription, but am I believe that simply resuming cost me $5? The UI really make it look like that was the original $5.
