Good idea but it needs a lot of improvement

I was hoping to be able to run my QSI CCD with this app and my MacBook Air. The app does not give obvious feedback so it's difficult to know what it's doing. Being used to other sequencing software the frame and focus routing is clunky to say the least. If I understand it well, opening the frame and focus window automatically makes the camera start taking exposures. That is a really annoying feature. i would prefer to have separate buttons to take one shot or a series, as desired.
The app responds very slowly to commands and sometimes it hangs making me fear that something bad is going to happen to my 5,000 dollar camera.
I was also hoping for a more intuitive way to define filter sequences and rotation through filters. The app only lets select two types of binning. One for the first filter, the other for the rest of them. I would like to have the option of selecting binning type for each filter. It would be nice to have the ability to cleadly define a sequence as a list of events that are listed in a time sequence top to bottom and numbered. Seems like an obvious layout to me.
Furthermore the zoon feature in the image preview did not work for me. It's great that someone has started a mac app for QSI cameras and that it costs only 20 bucks, however it doesn't seem ready for prime time. I don't feel bad about buying this app as I hope that the funds will help further developing it, however - alas - for the time being I am forced to keep using some more complete windows based sequencing software.

In essence I would love to have a better organized, easier to utilize, user interface. I suggest looking ad Backyard EOS as en example of elegant design and good user interface.
