Hi @Bernie,
Thanks for your feedback. We’re constantly adding new features to Thunkable X and 2019 is going to be even bigger and better.
The great thing is that you can still enjoy all the features of Thunkable X with your existing free membership. @darren has done a great cost-benefit analysis in his video here:
At the moment, existing extensions aren’t compatible with Thunkable X but I’d be interested to hear which ones you want to use and what sort of app your are building at the moment.
Thanks.
