+1. Not strictly dynamic tiling, calls to a lua script (a standard stack/master by default) to know where to
+    * Tile windows
+    * Follow window rules, (GIMP should be floating)
+    * If this is the case, a default config should exist somewhere
+2. A very transparent API for lua to interact with is important
+    * I love the idea of the autocommands, wm should hold a callback list for each autocommand (maybe look at how nvim does this)
+3. Is it better to use the zig-wlroots bindings, "translate-c" wlroots, or compile the C in with wlroots
+    * It seems like Isaac started with translate-c and then created the wlroots bindings. Depends if we want latest for wlroots and zig
+    * Not using the bindings is most likey a LOT of extra work
