STATUS: You can view almost everything in a data file, but editing might not be possible for some properties. Scripts are hit or miss.

I've been working on the Avalonia port of UndertaleModTool for a little while, so I decided to finally make a draft PR for it, in case anyone else wants to help. As discussed in #460 and elsewhere, Avalonia is probably the best choice, since it's multi-platform, works in C# and seems to suck less than alternatives. I tested the current build on Linux and it seems to work fine (except the performance).

Currently, I'm working on making it work as a sort of 'view only' UTMT, so those not on Windows can datamine games, at least. Of course, the architecture still has to be made such that we could later add editing functionality.

But, it is not complete yet. No, it is far from complete. Here's a TODO list of all the things I can think of that need to be done (but there's certainly more):
