MC version: 1.7.10
Mod version: 2.0.233

I've erased my previous comments and am finalizing the suggestions and problems by editing my first comment.

Before I start, I'm just gonna say it - BQ is such a wonderful mod with great flexibility and interaction with other mods, so thank you for your great work and the time and efforts invested:) Now here goes my suggestion and question.

Suggestion 1) Currently the variables in the lang file are not differentiated, meaning I have no option to switch the order of two or more variables in the same sentence. For example, "Completed quest %s for %s". Now for certain languages such as my native one, a smooth translation requires reordering of the variables, which I currently cannot do. Could you perhaps consider differentiating the variables in a sentence such as %s1 %s2 in a future update?

Suggestion 2) It would be wonderful if we could have some more in-depth guide of how to fully utilize the BQ mod. As a matter of fact, a case by case demonstration of how to achieve something would also be a great alternative.

Mistake) I think you made a mistake with the 'logic' string. If you press SHIFT on a created quest, the logic currently says 'task logic', so I believed what I saw and thought that the logic was 'task logic', not 'quest logic'. But testings prove that it's actually a 'quest logic' and not 'task logic'. You should fix this to read 'quest logic' instead of the current 'task logic', which is wrong and misleading :)

Thanks!
