Neat program! I like all the features, and the layout is very nice and clean.
It would be nice to have the current tsc file's name as a header while you're editing it, or maybe have it coloured in in the file directory listing on the left.
Also maybe it's just me but I think it would help to have the 'search command' box at the top instead of the bottom.
Lastly, it would be cool if eventually you added things like face previews, or things like mentioning what direction so-and-so fade number is when you hover on it, etc. But that probably takes a lot of time and effort and might not be worth it.
Now, I tried opening
a Japanese mod with this program and it largely works, but a few files (that i assume must be in shift-jis like all the others) were interpreted as being in utf-8 or cp850, and hence look like gibberish. I don't know what causes this, but it might be helpful to have a manual override for the encoding scheme.
Another issue is that almost all script files are cut off midway for some reason, which makes this unusable for now. I'm not sure if it's just my computer or what.
I've linked the mod I'm using, maybe you can see if these issues are reproducible. Thanks!
