Hi
I was an happy user of modify epub, but Linux distributions are switching to python3 calibre.
And the plugin does not works on python3. I know precompiled version of calibre is python2 but linux distributions make their own packages (and python2 is unsupported).
I have tried to modify the plugin, to works on python3 but I am not sure it is the best way.

Are you interested in converting your plugin to python3 ?
(I think it would be possible to make a plugin compatible with python2.7 and 3)
Thanks in advance
