I have been using Tree v0.1a, the initial release, for two good months now and I must say I am overly satisfied with the quality of the product. It has not suffered a single failure and is performing up to my expectations.
I know I am not in position to give constructive comments about my own creation, but I think I am well past the “This thing is the next Windows” point. Even if the framework is seriously alpha, I am not the only person who can use it (to a certain extent) and it has not failed miserably whenever I wanted to show it to someone.
Finally some software of my own making that did not get the boot halfway through development and that everyone can use(everyone visiting my site that is). Yes, defects and enhancements are piling up in Trac, but thats a side effect of improvement.
