-- loads the eGPU ejector spoon, which is STILL VERY MUCH NOT DONE

-- OWC has pushed an ejector tool for its docks. this kind of makes this spoon obsolete. 
-- keeping it in case this turns out to work more reliably than the OWC tool, but that's unlikely. 


-- hs.loadSpoon("eGPU")

-- loads the ControlEscape spoon, which is courtesy of Jason Rudolph
-- https://github.com/jasonrudolph/ControlEscape.spoon
-- I should really consider making this work for the Function key instead of Ctrl, easier to reach with short keyboard

-- -- spoon for doing a quick toggle of DarkMode
-- -- this doesn't work, and I don't have the time to figure out why, so it's disabled for now. 
-- -- it won't run with the key combo, but executes immediately when loaded.

-- === sizeup ===
-- SizeUp emulation for hammerspoon
-- stolen from https://gist.github.com/josephholsten/1e17c7418d9d8ec0e783
-- removed the bits I didn't want to use.

-- known issue: moving window to new monitor does not adjust menu bar. Active menu bar for that window
-- is still the menu bar from the previous monitor, until the window is interacted with ie made fullscreen

--imrovement: maintain current fullscreen state when moving window that is already fullscreen
-- way to do this: maybe "if fullscreen, then set fullscreen to false, then move"
-- maybe too janky and long. remove animations or speed up somehow?
