Thanks for the quick response! I don't think target memory requirements are an issue per se, since it's anyway the responsibility of the developer to make the trade-offs for their particular use case. It's more of a problem in practice if an authoring tool imposes limitations that are hard to work around. However, I do see how this request can lead down a deeper rabbit hole.
In any case, thanks for your work, CharPad makes life a lot easier already!
