* The commands are executed with 1-2 seconds delay. This delay is caused by the underlying launchpad hack which seems to execute a graphical notification before the command itself. The speed would improve automatically as soon as the launchpad speed would improve.
Hi. you mention a lag via lauchpad commands.
There is a paramater withing the launchpad config (um... or ini I forget)
to reduce this detection delay time, it is set to 700 (.7 of a second) by default IIRC.
Whilst this may not be 100% of the problem perhaps it may contribute?
enough time to mash 3 keys for we mere mortals
Perhaps playing with this value could adjust performance to your liking.
I don't run this so untested. Interesting use of mplayer though. perhaps I will.
