I checked VistaSwitcher. The same there. You can sort alphabetically each time by right-click but not option for automatically sorted.

You may check the alternatives:

Another idea is to use the Task Manager sorted by name. 7+TT lets you easy access to the Task Manager.

If you find something cool, let us know.

What about displaying the percentages by refreshing the tooltip?

Scroll the wheel while hovering the Speaker Icon, will change the volume. Instead of opening the Volume Bar, it will display the change by the percentages in the tooltip.

I can tell you that in HotkeyP you can hide the Taskbar by Hotkey.

Command: Hide Window

Parameter: Shell_TrayWnd

But it's only hide the taskbar, and does not pull down the windows above.

Also, I found that:

Take a look at here:

Nice.

Unfortunately, I decided not use those "volume wheel scroll options", because WIndows unmuting the volume when scrolling by mistake. It is not the behaviour I want.
To get over this problem I'm using HotkeyP volume commands. It doesn't Mute/UnMute automatically, but by a command.
I would glad to see what I suggested in OptionsEx.

Display seconds on the tray clock - Toggling by MiddleClick on Clock

Can also be good solution.
