Sorry for the late update. I have been extremely busy with my full time job, but I have still been hard at work on Tada using every bit of time I get.
But let's get straight to the point:
I have done a lot of optimizations and changes to the code.
Unfortunately some of those changes broke the application and I had to do a lot of refactorization to get it up and running again.
I'm happy to announce that it is working again and running a lot more optimally.
However it is now time to do a thorough test.
I will be doing all my accounting work on it and will see how it works in a more "Production" based environment.
As I'm still a sole proprietor, so I won't be able to test how it works with multiple simultaneous users, but I will be able to still test how it "feels" and runs.
I will upload V4.0 as soon as I feel comfortable with it.
