I would like to know about QGIS plugins from a user point of view, because some plugin lack some user case, and one doesn't know what to do with it. I guess a lot of great plugin are under-used because people don't know what it does.
Could you describe a plugin you like, what it's supposed to do, and specifically what you use it for and how you use it ? The best would be an answer = a plugin !
My question is similar to What QGIS plugins do you consider to be essential?, but QGIS has evolved since and many features have been implemented and some plugin are depreciated, while great plugins appear every day. I hope my question is not too broad. Any answer on any plugin can be useful in my opinion, even if the plugin is depreciated some day. I'll probably answer to my own question for some plugins I like and use a lot too.
