Thumbnail size

Hello everybody,

I installed Kdenlive from SVN and it is working good. This application is wonderfull..

So, I want to change some small parts of the code for my own use. But I can't found the codes that I'm looking for. For example, I changed the "video track bar" size in timeline(in projectlist.cpp, line 633), the timeline tracks are bigger now.

But I can't found the "thumbnail size" of Project Tree. Is there anybody who knows where can I change the thumbnail size?

Thank you!
