What even is the difference between profiles and layers?

Why is there exactly 3 profiles and 3 layers? Why are the hotkey combos not configurable? What's even the point of having hotkey combos if I have to look at the manual to figure them out? Why is the user manual hidden away on the quickstart page? I can't seem to find any obvious way to navigate to it from the homepage, and it's not mentioned at all in the downloads section, nor the product page itself Why is there random Chinese text in the profile export? That doesn't look like a Print Screen key to me

Maybe spend more time proofreading the manual instead of making it look pretty What is this checkbox even supposed to do? The wording on some things is just weird or poor Why is the software unsigned? It's pretty concerning to just host some random binary on your website and tell customers to trust that it definitely comes from Glorious and not anyone malicious. Honestly the user experience is generally really awful, here's a some of my complaints:
