I've had similar thoughts, though I had the same thoughts about Alfred in general at first. I get the feeling that there's lots of powerful things that will come from Remote in future, and that it will take a while for them to come out - especially as features get refined/added.
I need to spend some time really digging deep to see what I can use it for, but here's what I've been doing so far:
* Locking my computer when I leave the keyboard to go to the bathroom/kitchen/whatever and forget to do so
* iTunes control (as you mentioned)
* Controlling VLC. This is awesome, as I use my laptop to plug in to a big screen to watch films on, and can't be bothered getting up to change the volume/full screen the app/turn subtitles on/off, or delay/speed up the audio to fix lip synching. I've created a workflow for this if other people are interested. One question this use brings up is using the remote on multiple computers (like my wife's). Could I activate the powerpack on two different laptops and connect the remote to them both? Or would I need to purchase two powerpacks? I'm sure the answer for this is pretty easy to find, but these are just the thoughts as they come to my head.
* Spotify control. Writing an app to control Spotify as a jukebox like iTunes.
* Photoshop control. I can never remember the shortcuts for stuff like Curves/Levels etc, so maybe having my phone as an extra input device with useful icons will help. Will see if it's actually useful or just a nice idea in time.
Some sort of feedback loop in future versions would be great - with on screen displays for certain things.
Got a similar question here - https://github.com/clickysteve/alfred-remote-workflows/issues/1
Hit Remote at the top of Alfred
Click on the + icon in the bottom left
Select Workflows
Select VLC Remote Control
Select VLC
That will add in the Remote page for you to use in the iOS App.
I've been watching lots of films and making use of the Alfred Remote features lately, and thought it would be handy to be able to control f.lux remotely as well.
Features:
Trigger preferences
Quit Flux
Trigger Movie Mode
Trigger Darkroom Mode
Disable Flux for 1 hour
Disable Flux till sunrise
Disable Flux for current app
Works with Flux 34.0
Includes a general workflow to control Flux as well, though I realised after searching Packal afterwards this has already been done - so the remote part will be of most use.
You want to use 'key code' rather than keystroke for those sort of things.
on alfred_script()
tell application "System Events"
key code 125
end tell
end alfred_script
The key code 125 is for the down arrow. You'll need to add in 'using {shift down}' or similar to add in that operator.
