After over 7(seven) months of waiting for a update review in Ubuntu Software Center I got a reply from Canonical.
Basically they say sorry for the waiting and ask me for creating „Debian source package”. So far I use to submit zipped files with all necessary stuff and good guys at Canonical did the packaging. Unfortunately I have no idea about packaging and no intention to learn about it.
For now I decided to unpublish both apps in Ubuntu Software Center.
Apart from that, my personal circumstances changed and I have no time and motivation to develop Zeegaree any further. Maybe it will change some day. Who knows.
Good news at the end: I’m going to upload the source code for both apps on GitHub soon.
