It's probably going to be a while. In the course of converting to BG2 spells, I've decided to do a complete review of the spell system (for the most part, the SPPR* and SPWI* spells, plus Bhaalspawn innates and kit abilities), to correct any issues I spot, and to update spell descriptions to be both accurate and detailed in cases where they are currently vague. It's something I've wanted to do, and this is the perfect time since I've got to put my hands on all these spells anyway. But it takes a while to do a good job.
I may start developing the rest of the journal again side by side with the spell review, but I haven't decided that yet. I'll try to be better about updating the "Coming Soon" section of the changelog so you can at least know what's been completed, what's currently on the table, etc.
