I've a suggestion:
Open projects also without required plugins.
Dialog: "Missing addons" "The project you are opening uses addons that are not installed."
Please add a button to force loading the project without plugins.
a) Remove all events, etc. from missing addons.
b) Replace the events, etc. from missing addons with placeholders.
c) Mock the addons. (dummy)
d) any ideas?
This feature would be very nice. For example: Open a old project with unimportant addons.
In some cases, plugins are obsolete and no more available.
Workaround: Remove all missing plugins and references in caproj and other files (xml).
