This also shows how risky the usage of plugins from external developer is.
I really appreciate the work, the ideas etc. but from a user perspective it’s a risk to use them vs “build-in” and supported versions.
There are many reasons why the dev. for a plugin can stop and as a user of a free solution you have only minimal influence to that topic.
For example I used the imgur plugin but it seems that the dev. can not find a solution for live preview.
That teached me the hard way to be more carefully with the selection of the plugins.
