That’s a good question,
WooThemes are now taking a different approach to Canvas – so instead of re-writing they are going to evolve it going forward.
Their focus now is really woocommmerce hence the slowdown on canvas updates over the past year.
In terms of our approach – we took all our learning from being big fans of canvas over the past 5 years and built that functionality into 18tags.
Canvas still has it’s place in our armoury but you’ll see more and more updates going into 18tags pro over the coming year. These won’t be as extensions, but will be part of the core product :)
I hope that makes sense,
