MAMAMAC  The program is very stable, i've been using Yojimbo for a while now, like its slick look and its simplicity, the problem with Yojimbo is that there is no nest folder. Unlike Eaglefiler, it let you have nest folder, well, it's great. I now switch to Eaglefiler, but the problem is that, it's slower than yojimbo on my ibook g4, which run smoothly with yojimbo, but eaglefiler, it slows, and take very long to load. i hope developer address this issue.
