I was recently discussing an idea furanku in a different thread, and I came up with another idea that I thought I'd share in a separate thread.

A lot of plasmoids in KDE4 are made for certain features, and they do their function. However, a lot of time these plasmoids are completely unnecessary, and so they should hide and free up the space.

As an example, here are three plasmoids that are sitting in my panel and are doing nothing at all other than being pretty and taking up my taskbar real estate: Battery monitor, device notifier and the wireless meter.

I keep them in the taskbar for obvious reason: when I'm unplugged, I need to know how much battery I have left, when I plug in a flash drive, I need to easily open it, and when I'm on wireless, I like to see how good the link is.

The propblem is, though, that as I'm sitting here right now, I don't need any of those. The battery is charged, the device notifier is empty, and my wireless radio is shut off. And since I like my taskbar two rows high, these plasmoids are pretty big - about 160 pixels - which is about 1/10 of my taskbar!

So my idea is to have a function call that a plasmoid could use to let plasma know that it is useless right now can be hidden. If it is in a containment that is of limited space, like the taskbar, plasma would hide it until it is needed again.

So, for example if my laptop is plugged and fully charged, the battery monitor would disappear. As soon as I unplug it, though, it reappears.

Of course, if you want to (re)move it a plasmoid, it the hidden ones would appear whenever you open the widgets dialog.
