This is really close to what I've been wanting to build for a while. A sort of excel for programmers with the added ability to write real lua or python code in each cell instead of "formulas".

BTW, I'm suprised this is written in Qt. Looks very modern Windows, in a good way of course :^)

I've been meaning to check out sc-im ("Spreadsheet Calculator Improvised" https://github.com/andmarti1424/sc-im) for a while now. Among its listed features:

> GNUPlot interaction.

> Scripting support with LUA. Also with triggers and c dynamic linked modules.

> Implement external functions in the language you prefer and use them in SC-IM.

Does anyone here have experience using it? Is it stable and reliable, and does it handle large files well?
