10.7: Remove items from Launchpad System 10.7
Although this is not really an easy way of doing this, I've decided to share this hint, because the impossibility to remove anything from Launchpad was really annoying me.

Use this hint at your own risk! Be sure to have some kind of backup available.

Here's how:
  • Using Launchpad, create a group of items named 'Trash' and fill it with the shortcuts you're wishing to remove.
  • Unhide your 'library folder' (See this previous hint, or use your favorite method).
  • Backup your Launchpad database located in ~/Library/Application Support/Dock.
  • Download any sqllite query editor (Navicat Lite is very good and free).
  • Open the Launchpad database with Navicat.
  • Run the following query:
delete
from
  items
where exists (
  select 
    i.rowid
  from 
    items as i inner join 
    groups on i.parent_id=groups.item_id 
  where
    groups.title like 'Trash' and
    items.rowid = i.rowid
)
Remarks:

The database is taking care of data consistency via triggers (triggers will remove images caches and reorder items).

The good point is that the (now empty) 'Trash' group will remain.

[crarko adds: I haven't tested this one. As mentioned in the hint, please be careful and have a backup handy before trying this. I have to say, Launchpad is one of those features I'm kind of 'meh' over. I have no interest in reorganizing the thousand-plus applications I've got into folders again. Maybe on a new machine.]

Note, that any apps purchased through the App Store you can remove just like you can on iOS.

Which is fine, unless what you're looking to do is clean up LaunchPad to show a select set of applications, yet not delete any apps excluded from LP.

LP is a find idea, but entirely under-baked, i.e., nearly raw in terms of usefulness at this stage.

Hopefully it will gain easier management (I don't have hours to spend arranging seven screens of apps I didn't want there in the first place); and gain alpha-navigation (once I see the app I want, I should be able to type its name's starting letters).

It could be a useful tool for when your can't recall the name of the app you want in order to use Spotlight (Alfred, QuickSilver, Launchbar, et al).

Hi, there's a small and free app for cleaning/restoring Launchpad items with 1 click: do a google search for launchpadcleaner, you can download it form the zoltanb website

You can do this all right from terminal with a single command.
sqlite3 ~/Library/Application\ Support/Dock/*.db "DELETE from items WHERE exists (select i.rowid from items as i inner join groups on i.parent_id=groups.item_id WHERE groups.title like 'Trash' and items.rowid = i.rowid)";killall Dock

If you can use that Terminal command to remove the "Trash" folder, then you should be able to use a similar command to just remove the desired app(s) directly. I'm not inclined to figure out the exact syntax, but maybe someone else is.

I also wanted to clean up my Launchpad screen, but hadn't found the time to use this hint.

Then this morning I came across the free Launchpad-Control app. I'm going to give it a try tonight.

Looks like the Lion mods are starting to hit.

I think many users underestimated the power of this method. With little changes this hint would be very powerful if the query will be converted to a trigger. If so, simply putting icons on the Trash group will automatically delete it.
Anyone with sqlite knowledge can convert it to a trigger?
