I'm very busy with university at the moment and it's also only a few days until christmas - so my spare time for Mp3tag is very small.
I read all posts and keep a internal list of post I wish to answer, or where I have to throw a decision. I sometimes need several weeks to decide about a specific suggestion, but as you can see on the forums almost every post is anserwed by me, Sebastian or dano.
I usually also have a priority hierachy from critical bug reports to simple suggestions - so please be a little bit more patient on replies for suggestions. I also get about ten support requests, suggestions and bug reports a day per simple mail. These ones should be answered also.
I just came home from university while I get up at 6:30 this morning (yes, this is a long day!). Now I have to pack my bags, because I'm visiting my parents this weekend. Tomorrow I'll get up at 6:30 again and will leave the town at the end of my lectures at 17:00.
I hope you understand, that I'll not decide about the availability of scripting functions at FTF atm. But I also hope, that you know now that I'll not forget to answer your question before the next release of Mp3tag.
