Is it possible to edit plugin parameters using administration web panel?

Question

When developing a plugin for atlassian products, usually there is a need for some configuration parameters, related to that plugin only. I've read so far about using atlassian-plugin.xml to store these parameters, using <param> or using plugin .properties file (in src/main/resources).

Does JIRA (or atlassian in general) provide administrators with a way to configure plugin parameters through the web administration panel in contrast to editing files manually?

To make this more clear, when an administrator logs in to the administrative area of the JIRA (for example) and clicks on Plugins (to manage all the installed plugins), the list of all the plugins will be presented with the possibility to check each plugin details. Is there a way to click something in those plugin details to get the simple configuration dialog (hopefully defined in atlassian-plugin.xml file, as a list of fields, with their name/type definitions) for that plugin?

Yes, you can include administration panels and code in your addons.

Exactly how you include one depends on the plugin type you are writing, but it's generally as addon panels to the administration screens, rather than via the UPM screens, and each panel for each plugin tends to be different - some plugins simply can't support "a list of fields".  You need to define the full chunk of code behind the panel (so the classes it needs, and the velocity macro to draw it, at the very least)
