It would be nice if you could flip a switch and have the little button call itself a 'Quest Log' instead of a 'Todo List' and call items on the Todo list 'quests'.

Hahaha that is a really nice idea.
I added an issue for this: https://github.com/JonasJurczok/factorio-todo-list/issues/74

DarkStar series anyone? :D
Fantastic!

Feel free to suggest more different patterns.
If someone provides the texts it should be interesting to implement it :)

I'm the one who provided the DarkStar series with an alternate version of the mod file that had the new text hacked into the language files. Which is a terrible way to do it. :-)

:D I would go the "lets have a setting with multiple text styles and pick the correct translation accordingly" path..

Is it possible to pick alternative translations for the same language out of the file? That was a thing I was puzzling over. The relationship between various GUI components and the string plucked out of the language file doesn't seem like it's amenable to being altered in Lua.

Not by default. But what you can do is add prefixes/suffixes to the translation key. E.g. "todo_title" vs "todo_title_quest".

Then you can provide different translations and pick the text to be used at runtime.

There is a new version released that now supports "quest mode". If you have suggestions for the text (or translations) feel free to ping me :)

I've been meaning to go through and do just that. :-) I noticed that at least one thing was missing a translation, but I didn't write it down, so forgot which one it was. :-)

:) If you find it again just tell me. :D
