Sure, it could be presented a little differently and more options for front-end appearance would be nice; but, hey, that applies to almost anything.
I can work with the way it looks because it does exactly what I need.
AND the service is fantastic.
I had a display problem on installation - they just went into my site and fixed it - no fuss, lovely responses and good service.
You want a comment/feedback box? This is the one!
1 I set up a 1.54 site and all went so easily well
2 I then created a 1.6 site and, again, installation and using it was a dream.
I had one problem and submitted a ticket - the response was in minutes - and we found that it was due to using Firefox 6 beta. Otherwise I still have no problems and am delighted with this excellent product and support
