(1) By poor support I mean it took too long for someone like me, has has purchased a premium extension, to get a reply to a support-request email i sent. I have bought premium extensions before and my experience has been to get a response within an hour from the vendor. Note, it’s not in all cases I had needed support. If the product is intuitive enough or documentation is spot-on, I most likely wouldnt need to send an email asking for help.
(2) Your documenetation could be way better. No images, no ‘snips’ to illustrate what you are saying. A picture is worth a ‘hundred’ words you know. Plus one important link in your documentation led me to a 404. I didn’t save that link and won’t bother to find it for you. I know you can find it yourself if you really want/wanted to correct it.
