Congrats on all the great work! It sounds like you're doing a great job!

If you've got a screen top, you can put a damp towel across 3/4 of it to bump the humidity... it goes up 10-15% for me (sometimes I have to do it during shed- it's a bit dry here sometimes). Other than re-wetting the towel a couple of times a day and changing it out every 2 days or so, it's a low-maintenance way to get more humidity.

I still haven't made the F/T switch myself... How long have you had her? I seem to remember someone saying you should wait a couple of months (to let her get used to everything) before trying the switch, but it might work for you right away.
