My snippit is to change the DB TABLE name, not the advanced name for developers...you might have to talk to support to get a script to do that. I'm sure it's doable...
This is one of my main SF Forms gripes, the naming sucks. Way way back, those autogenerated (totally crappy) dev names used to be what showed up on the EXPORTS, not sure if that's still the case, but maybe.
What needs to happen is a Regex needs to run as the user types, like on creating a page, and the Advanced name "Suggestion\Default" needs to be based on the Name\Title, not the ID or Control type...it's just insane this hasn't been addressed yet. I mean there's always something to address, but this is (aside from no permissions) a HUGE problem with forms thats inconsistant with the rest of the CMS.
I just tell forms editors to always open that up and remember to set the "developer name"...it's insanity. Heck even I forget to do it sometimes...like 10 widgets on a page, maybe I forget on 1....and it's set for life.
