I switched to KDE, so I won't be working on it anymore.
This extension activates a XBindKeys-profile per application or window-title.
https://extensions.gnome.org/extension/2755/xbindkeys/
git clone git@github.com:darkretailer/gnome-shell-extension_maxi.git ~/.local/share/gnome-shell/extensions/XBindKeys@darkretailer.github.com
If "autocreate" is enabled this extensions creates a file per Application or window-title. You can open the directory containing this files via settings-menu.
~/.config/xbindkeys
Please disable "autocreate" if not working on your XBindKeys-configuration.
