Other functions of WB are working very nicely for me. I am using WMECH in non-integrated mode and it's extremely nice to have. With the recent cap on 150 edits which count for points per save, the auto-save feature is very nice to have. It still surprises me, but probably "saves" me from losing points.
I'd like to see the slider be able to be adjusted higher, maybe 150, even though there is no direct relationship between changes and edits.
Related: the WB save button uses the word "Edit" which isn't totally accurate. "Changes" is rather long, though, so not sure how you want to address it.
