could you be a little nicer please? :P I'm tired of people snapping at each

btw, I've only had a quick glance at what you guys are doing, but here's some 
food for thought: the user is most likely to care how much free space there is 
when there isn't much of it. (although with 1TB usb drives it becomes a bit 
hard to quantify "not much", hmm...)

let me quote the relevant bit that you evidently missed: "and provide the 
usage text where the current progress bar is."

I guess you don't have a portable MP3 player. If you had one, you wouldn't 
make such ridiculous proposals.

Colors, pie charts, etc. are OK for quick and dirty checks -- for disks that 
have hundreds of gigs available and a single MB isn't of any significance.
With common MP3 players a single MB makes the difference if I can have a song 
stored on the device or not.

Design decisions that require tooltips or additional clicks to find out basic 
information (be it space available on external drives such as MP3 players or 
Plasmoid descriptions) are counter usability and may have their space in the 
realm of GNOME.

is it worth the extra text (and therefore visual 
information) in this particular UI to always show the numeric amount of space 
left?

that you can find this out on hover via a tooltip is not 
particular discoverable, and this information only shown on hover of the item 
anyways.

i really dislike text-on-graphics from a design perspective. 
text is fine detail, and a progress bar is visually fairly complex. maybe it's 
time to think outside the box. e.g. maybe colourize the device icon showing 
what % of it is filled and provide the usage text where the current progress 
bar is. the pie chart solution as seen in Lancelot would likely break up the 
layout in visually unpleasing ways here, so i wouldn't consider that too 
much.

How about extending Plasma::Meter to show text/numbers in the progress bar? 
Maybe it could look like the percentage display on the battery Plasma applet.

I agree, suggestions?

Indeed, since Qt 4.7 would probably be required for KDE SC 4.6, I agree that 
I could in principle leave it as-is. 
 
> What are the actual improvements then?
I'm just trying to experiment early in the release cycle to see if I can get 
some good ideas;
The point is to make sure to have a consistent look; right now the look of the 
capacitybar 
depends on the qt widget style, which doesn't sound exactly right to me.
I mean... I can live with it, but I'd like to come up with something more, 
well… elegant :)

No longer displays amount of free space --> regression.
Avoidable tooltips -> Usability problem.

the tooltips don't cover this scenario explicitly right now, but the code 
shows a lock/unlock button for this two-step process.

Would it be possible to list the other devices in the tooltip?

Also, how does this all deal with encrypted removable devices, where
you have to unmount the partition in the encrypted volume, then
unmount the device itself?

good idea. the strings you committed:

"Device is plugged in and the volume can be accessed by applications. It is 
not safe to remove this device."

"Device is plugged in and the volume is not mounted for access yet. The device 
can be safely removed."

"Device is plugged in and the volume is not mounted for access yet. Another 
volume is accessible on the same device, which cannot be safely removed."

i think we can assume in all cases that the device is plugged in. if it 
wasn't, we wouldn't be showing it :) so let's just remove that part.

i think we should also start with the important bit: if it is safe to remove 
it or not. and let's try to drop some of the jargon, such as what "mounted" 
is.

so .. maybe sth like:

"It is safe to remove this device."

"It is not safe to remove this device: applications may be accessing 
it. Click the eject button  to 
safely remove this device."

"It is currently not safe to remove this device: applications may be 
accessing other volumes on this device. Click the eject button  on these other volumes to safely remove 
this device."

the eject image can be added to the tooltipcontent with:

addResource(Plasma::ToolTipContent::ImageResource, 
"devicenotifier://eject.png", ejectPixmap);

thoughts?

Show error messages inside the applet instead of using Plasma::MessageBox
