Regarding moving corridor items:
it needs right mouse click. if you open /opt/CorsixTH/Lua/key bindings.txt, scroll to bottom and remove -- from entries for binding x and z to middle and right mouse.

when mouse is over bench press z to pick up. reception desk is a bit more awkward. click elsewhere, drag over desk. without releasing touch screen, press z and then drag to new position. problem is desk has queue function activated on left click.

built 0.30 (without movies but with patches from repo 0.2.x version. it still suffers chart crash. on an off topic note its the first time my laptop has been able to connect via bluetooth since arch switched to bluez5.

there is an android port which allows long click to simulate right click. will look into at some stage.
