Synaptic: select packages by task on Ubuntu 11.04

[lucacerone]

Dear all,
I've just finished installing Ubuntu 11.04 on my computer.
I wanted to install LAMP server, but I noticed that the
option to select packages by tasks has disappeared from synaptic.
Is there the option to re-enable such a feature I found it very helpul?
(Don't worry about LAMP, I've already installed it following some tutorial,
but I am just interested in restoring the "Select packages by task" in Synaptic).
Thanks a lot in advance for your help,
Cheers, -Luca
