I am Antonio and I will be happy to help you out with your issue.
I am afraid that this is not possible to do with our plugin, autofill the fields is a browser feature, the user has to at least fill the form once in order for the browser to store the data.
You could use javascript to store the data (after the first time the user fills the form) and then reuse it, but as I said this is a browser related feature, our plugin cannot do that.
Here a link that can help you if you want to use Javascript: hidden link
Sorry, may be I was little unclear, but it seems to me that there is nothing special to get a name for a word-press LOGGED-IN user and put it in a Toolset contact-form field by default and also email.. You don't need browser memory, you need just to get user - name from wp?
Sorry for the late response as Antonio is busy with other tasks. This is Minesh here and I'll take care of this ticket and try to help you further. Hope this is OK.
Well - as you mentioned this is contact form, I would like to know here, is contact form will be accessible only to loggedin users - if Yes: then Yes, we can autofill the info based on loggedin user info.
If form is open to all users (without loggedin) then I would like to know how you want to manage this ?
