The modifiers contained in the VCSA file describe color, which is also (probably) also used by vim for the visual mode.

UTF-8 and scaling, perhaps even fonts should be implemented

Update to OCaml 4.07 (or at least 4.03) to get access to the improvements to stdlib and some packages (e.g. dune).
Raspbian only has OCaml 4.02 and opam in its repositories which should be enough to compile OCaml 4.07 or load it via opam but this did not work previously for some reason.

Currently the program loops over the file contents of the VCSA file, essentially busy-waiting for changes. This can be improved by using inotify and will also reduce the CPU-Usage.

Rewriting the driver in OCaml has the benefit of using only a single language. The performance impact of this should also be negligible because no weird pointer-arithmetic is used in C. The arrays used in C can also be translated to OCaml efficiently.

Currently the changes in the VCSA are fetched and a simple bounding box is updated on the screen. This can be improved by using multiple smaller boxes that encompass all the changes.
Before implementing this, the program should be profiled to ensure the best ratio between unnecessary redrawing and many inefficient tiny draws is found.

Currently the drawing algorithm results in weird artifacts. They seem benign but this should be adressed nonetheless at some point.
The position of the cursor can also be incorporated into the algorithm to show the most relevant information first.
