This is a good idea.

I had been thinking about doing something like this for 4.11. My main
motive was to give the user a somewhat better idea of what is going on when
nepomuk/virtuoso are consuming resources.

I don't particularly like the idea of giving users the ability to stop
services, as that is too low level. They shouldn't need to bother that
much. In my head I was thinking about reporting the following -

* Nepomuk File Indexer
** Exactly which cleaning job is going on - mimetype, invalid files, etc
** Exactly which file is being indexed
** How many files are remaining? Maybe some kind of progress window?

* Nepomuk File Watcher
** Report when the metadata of a file has been moved or is in the process
of moving. This is useful when a large directory has been renamed.

* Email
** Tell them which email/contact/whatever is being indexed
** An approximate progress window

The user should be able to suspend/resume each of these processes, or maybe
even delay them for later? But they shouldn't be able to stop the process
all together. Cause these services are there for a reason.

My OCD is going crazy. I have this annoying super power where I can notice
when stuff isn't properly aligned. Down to single pixels.

We will need to improve this, but it is a great start.

Where do you think this should be placed? kde-runtime? Another repo? It's
UI stuff so it's not going in nepomuk-core.

Any thoughts, opinions and comments are welcome.
