I have been using one of those for about a month, and I absolutely love it. I have multiple display profiles, all acting as triggers for custom functions when switched to, using the Stream Deck as the macro button to switch profiles is a bliss. It is a bit annoying that I have to come up with all these different keyboards shortcuts though.

It would be amazing to see a plugin so we can directly assign DF profiles and custom functions to it in the Stream Deck software.

I can not beg enough for this integration. I would use it without exaggeration 25x per day

If it's just for switching profiles, afaik you don't need to assign shortcuts.
You could just use the DisplayFusion Command Line Tool:

e.g.:

I have done it since then. But I'd still like to see a plugin, as it's just more convenient to drag and drop functions onto keys.

+1 from me too, I would love a plugin and/or profile. Lots of abilities in DisplayFusion that I don't remember all the shortcuts for and being able to put them to an icon on my streamdecks would be awesome.

I cannot explain enough how much this is needed. Not only would it give DisplayFusion added exposure but it would give streamdeck thousands of more uses. Check out their list of pluggins on their site. I would actually pay for this plugin

+1 from me also!

I also would dearly love to have a streamdeck plugin to allow direct control of displayfusion functions without requiring keyboard combinations.

+1 for me as well.

This has been a HIGHLY requested feature for going on 4-5 years now it seems (earliest posts I see asking for it 2021/22
I think its pretty clear that its in high demand and it should be a priority by now. especially for how much money some of us are putting into these devices, we'd LOVE to get the most out of em...personally I have 4 stream decks and the pedal...and pretty much the only thing I can't do that I need to do at this point is control my monitor configurations for my 4 monitors - and if I'm in the middle of something it can be a real hassle to load up the program everytime i need to change setups - especially when I frequently switcvh back and forth between workflows.
I'd pay for this pluggin - nothing unreasonable but its definitely overdue and needed! <3
thank you!
