first I have to say with joy -> this is one of the best plugin (to me) for WP. I like it.
But, as a steady user I have 2 suggestions:
1. Link, image inserting
I have some tables with many rows where inserting links or images through insert buttons is really stunt. (write html code even more). Maybe same buttons at top of table template could help, or inserting button panel visible at mouse-over the table cells.. or something similar..
2. Column sorting
Cool feature, but useless with numbers or date, time sorting.
Thanks so much again for this cool WP plugin.
All the best and have a nice days.
