Package: jumpnbump
Version: 1.60-3
Severity: wishlist
Dear Maintainer,
the current version of jumpnbump-menu is written in python2 and use
gtk2.
Python2 will be in end of life in 2020 by the upstream.
gtk2 will be removed in one or two releases.
This is a draft (in attachments) for updating jumpnbump-menu to python3
and gtk3. The standalone mode and the options work, but there are still
some problems:
- server and client modes are not correctly selected
- the windows are not translated
- the about windows has a strange behavior when requested to close.
I don't have currently the time to work on it but I plan to do it in the
future.
Stéphane
