Not really; it's main use case is the following:
- prototype a gst-launch pipeline
- once working, just replace gst-launch by gst-gengui, and you should
now be able to manipulate the properties

I am truely sorry about the packaging, it's my first trial at it.
Improvements of the installers are on their way.

I didn't test it on a 64 bit system. Thanks for your feedback.

Yes, it is intended as the placeholder of video previews. This tool
has been originally needed for testing live bitrate modifications for
video encoders. For every xvimagesink that is in the pipeline, it will
be added to this very area. I will try to remove this space for
non-video pipelines.

Ok, i will try to catch errors and add some error popup then.

Thank you very much :) Very appreciated. I posted your remarks in the
issues tracker, expect some fixes soon.

Cheers
