Autofill
Jancy has a decently robust autofill system that works in conjunction with it’s profile system.
The v1.3.0 version of Jancy includes a new autofill system that attempts to work around some of the deficiencies of the old system. The new system includes the ability to perform autofill by simulating a user typing at a configurable number of words per minute if you’d like it to. Opting into the new system and all the related settings can be found in here.
