I got a zoom/pan feature working for the previous version without too much difficulty, I don't think I have the code anymore but it wasn't more than ~40 lines of code total. The other PRs on the GitHub also include a very nice bus implementation that you may be interested in taking notes from. One issue I did notice with the zooming is that while the internals of a chip could then be any size, the number of pins were still limited by the sides of the chip, and busses alleviated this problem mostly but not completely. It might involve some restructuring, but adding pin chips that can be placed in the workspace would likely solve this issue.
