Optimizations like that will be part of the next alpha release after the one I'm working on.
Glad you hear you are planning to look at it though :)
I assume your term library doesn’t create the actual table? So you’d know the term height and you’re then plotting the cells? If that’s not the case then I don’t think you’ll get much further with this project without switching to another term library (or rolling your own — which is actually easier than it sounds).
