I wonder why I can't have multi-docks in Mountain Lion

You could set up different screens in Launch Pad. You could then group your apps.

Different screens? You mean different folders to group applications?

I meant different screens but folders is certianly a good option.

Document Creation:

Graphics:

Music:

How to use Launchpad to do this? I think you meant in reality Spaces to do this. Not Launchpad. Or how do I set up different screens in Launchpad?

DragThing would do this.

You can move things from one page to another in LaunchPad. Just click and hold on an icon and then they wiggle and you can move them around, like you can on iOS.

Still, it would be tedious to move them all.

Oh, this kind of screens! 🙂

Yes, this would work like in iOS but I think it would be really tedious to walk through innumerable thematic screens.

While nobody appears to be writing a program to allow different Docks, you can create folders for all of your different tasks. Pick a location in your home folder to store the folders. Into each folder create aliases to the programs for that task. You can quickly create an alias by dragging the application from the Applications folder into those folders. The OS makes an alias when you move things out of the Applications folder automatically, now.

Drag each of those "Task" folders into the Dock.

I have only just upgraded to Mountain Lion but my two additional docks on the right and left screen edges generated by Dockit (Gideon Softworks, <http://www.gideonsoftworks.com/>) seem to work pretty well.

I'm still using the previously free Dock Spaces v3.15.

The current version is no more free though: http://nscoding.co.uk

It sort of works, but there's a glitch possibly caused by the Dock relaunching too fast – apparently faster than the corresponding preference file is being moved by Dock Spaces to the Preferences folder, thus causing the previously active Dock to reload yet again.

The workaround is to relaunch the Dock once again about 20 seconds later which then usually loads the proper Dock.

For that I have simply added a simple AppleScript to the global AppleScript menu:

tellapplication"Dock"

quit

endtell

Alternatively you can also open the Dock Spaces' preferences window and relaunch the same Dock from there. Or use any other utility capable of relaunching the Dock.

In any case, the crucial step is the 20 seconds delay though: 15 seconds doesn't seem to be enough.

I just tried the Docks 2.0.3 demo version, and apart from a bug that app icons are invisible, it also works only when the Dock is being relaunched 20 seconds later again.

Edit:

Thinking of it some more, I have now added the delay directly to the script, so it can be selected right after the Dock has been switched, without having to count the time "manually". 🙂

It will do nothing for 20 seconds, and then it will relaunch the Dock:

tellapplication"Dock"

delay20

quit

endtell
