I sure do love how modern Windows UI has decided that important things go in the bottom left corner.

google email composer? bottom left corner.
google email delete button? bottom left corner.
notifications? bottom left corner.
window resizing? bottom left corner.

okay, there's way more interest in this than I was expecting, so maybe I should post about it.

nextpnr currently has two placers: `sa` [simulated annealing] and `heap` [analytical placement for heterogeneous FPGAs].

`sa` amounts to "make a change" (e.g. swap two cells), accept it if it's […]

I've been working on a new placer for nextpnr.
