It might not be a 'trick' per-se, but anyone who intends to use a Mac for work should consider upgraded memory (IMO).
I did feel a little duped when I learned that some M1/M2 machines can only support one external monitor. Now I have to replace my two monitors with a widescreen.
I'm going to keep an eye on ram usage for the next few days. I'm curious what it will look like on a more full workload because if things have been swapping out, I haven't noticed.
You can say that it was my dad's mistake to buy an M1 8GB but I say it was pretty lame of Apple to sell a computer that expensive that can't do basic tasks. And don't even get me started on peripherals like external monitors.
Peripherals have been fine, except for monitors as you mentioned. I do think it's ridiculous that I can only have one external monitor when it's clearly able to support more than that. I can add a third monitor through my iPad or DisplayLink, but both of those methods breaks DRM video.
