Questions about plugin availability or usage, as opposed to those that are development-centric.
Tagged questions can be either about plugin usage or plugin development:
- How do I use X plugin?
- Do I need a plugin to accomplish X?
It's preferred to use the plugin-dev tag when knowingly discussing the construction of a plugin.
However, it's not always obvious that plugin construction will be necessary to accomplish a specific task. Or perhaps the intended goal can be accomplished by a plugin which already exists. In those cases, simply tagging with plugin is acceptable.
