Progress update:

Basically, what happened is that I spawned those vias around the BLDC controller to see what kind of space I needed to have for ICs. I extended the PCB 5mm, which gave me loads of room. Looking at the Tetrinsic 3D model, I reduced the PCB by 2mm. Then I moved the backlight circuitry and EN passives so that they were much closer to where they needed to be.

And then I tried this for the very first time:

I was thinking that this was going to have some cool marker where you can drag a dot-to-dot of lines as a placeholder for traces. This is what it actually did:

Have you ever heard that sound effect of explosion magic charging up? That's the sound I was thinking of when what would've been at least 15 seconds in EasyEDA was reduced to 1. And it only took a few minutes to find out that the Unroute commands in the Inspector were the ones that I jumped over to Fusion 360 Electronics in the first place:

For some reason, the Unroute command in the toolbar is rather subpar, basically acting like EasyEDA but I can just click to delete instead of click, delete button, click, delete button.

These 2 commands, QuickRoute Airwire and Unroute Connection, allow me to place a component somewhere, click to see if it's even possible to route, and if not, try again.

Additionally, I rotated this component and all I had to do was press Reroute and an N$23 pad. This would've been an entire event in EasyEDA, first deleting the traces, rotating and then placing them back.

I changed the order of the ADC inputs for better routing, as well as remove a capacitor for the wheatstone bridges to share since they were getting so close that there was probably little difference in 2 vs 1 capacitor.

Oh, and I've still managed to keep the ADC and BLDC controller in a circular pattern around the origin.

Moving on, this is the reason why I should be able to go with a slightly larger PCB:

For something like #Tetent TestCut [gd0139], the effective size isn't really all that different. Speaking of which, the square needed is 100mm now, up from 92mm.

There's also the other benefit of having enough space to put "Tetrinsic" branding here. Reminds me of XILINX FPGA branding:
