My apologies for the lack of updates, or much of anything. I’ve unfortunately been dealing with personal illness, as well as just being swamped with things at my paying job. Couple those things together, and WP-Slimbox2 kind of gets swept under the rug.
That said, I haven’t abandoned it plugin, and I really hope I’m able to squeeze in the time to release the next major update. I’m also hoping to get back to people regarding some of the issues they’ve encountered. If you’ve got a question, please remember to post it to the support forums!
