Did not work with multiple choice (checkbox) options - would not select anything.
Would be nice if there were multiple profiles.
I'm not able to create my own field types. Store number for example. :(
I love this. Few Features i wanted are 1. event clicks 2. shortcut to trigger this app
I cannot even stress out how helpful this extension is when testing huge forms.
Work very well.
Nice. But doesn't recognize date/time fields. Puts text in them.
Absolutely amazing!!! For a stay at home mom who does surveys as extra income this has saved me 30-45 mins!
Very helpful for development testing... More variation between forms and subsequent clicks on the 'Junkfill' button would be nice (aka, not always using the same name & info).. and I've noticed that it always seems to select the 'No' button for yes/no checkboxes, esp. optins.. it would be nice if that was configurable, as I test a lot of optins, and I want 'Yes' checked.
Can't disable default.
