Topic: Thumbs ordering

I have read somewhere here Felix saying ordering of thumbs was from left to right 1st, then down one row..etc.

Is there a way to change this or not?

I'm asking because i want to create a full picture from the thumbs display, and calculation is a bit tricky, and I am used to order by column rather by rows ;-(

But if it's not possible, then OK, I'll do it anyway.

Thanxx for your input and this wonderful tool.
Cheers. :?
