Hi Stojan, To stress the central part of Mojca’s longish message, it would really be best if you could get some people to work on the patterns and come up with a file that is definitely better than the current one, so that we can simply replace the current file. Contrary to her, I do believe it’s entirely possible for patterns of unoptimal quality to be in use for decades without anyone reporting it -- unfortunately it’s very hard for us to get people to give us real feedback. I do in any case remember seeing some weird things in the Bulgarian patterns.
In any case, if you do come up with a new set of patterns, we recommend the MIT licence (https://opensource.org/licenses/MIT). It’s a very simple licence, and -- as any free software licence -- it allows the authors to formally retain the copyright. If you use someone else’s file, the conditions they put on them it apply, of course. Best, Arthur
