Having delved into the twitter card stuff for the first time the other day I have a request that I'm sure you're planning on implementing anyway, but as a user I would like to say this would be very handy ...
Is there any way to have an option in a post (and more importantly a product) that allows to select the type of twitter card to be used? Ie summary (which is is fixed to now) or summary_large_image or product etc?
This would be a very handy and simple thing to add and would make this function a lot more useful.
Yesterday I altered your code a little to make it default as the summary_large_image rather than summary, which for me is a better option to have as standard, but this will obviously get wiped by the next update and to have a choice for different situations would be great anyway.
Thanks very much in advance.
