Which Plugin Type to Choose?

I have a pretty basic question:
I have a plugin that uses a dialog to get some values and then creates a bunch of objects in the current scene from data it loads externally. You might call it an import plugin.
This sounds like it should probably be a "Tool" plugin?
I coded it as a Tool plugin (RegisterToolPlugin) and it kind of works, but there is the kind of weird question on how to indicate back to Cinema when the plugin has done it's work and should give control back to Cinema. Right now, after it imports everything and the import is done, the cursor remains stuck with the icon of the plugin and I can't interact with the objects just imported.
I'm clearly missing something...
Here's the code if anybody has the nerves to have a quick look:

Hi,
welcome to the Plugin Café forums
No, a ToolData plugin is not the optimal way to go here. This plugin type is made for Tools, where the user interacts with the scene via the viewport (e.g. Move Tool,..).
Of course you could implement it as a CommandData with a dialog to get the additional values.
But for an importer actually SceneLoaderData is the plugin type to use. Unfortunately I only have a C++ example at hand (stl.cpp). In Python there's only an example of a SceneSaverData, but as it's more or less just the opposite, I guess, you can still get the idea: Py-IESMeta.pyp.

Thx for the input! That was exactly my "foobar".
I changed it to a Command plugin and it works as intended now. I'll look into the SceneLoader to figure out whether that will give me any advantages.

One advantage of a SceneLoaderData is for example, that file of this type can be dragged directly onto Cinema.
