-Added "untargetable" generators and receivers
-Added the new composite meshes section (metal+medieval combined theme + simple guidelines to group and create composite meshes-walls and fences to reuse elsewhere and give levels new looks in a tidy way)
-Added new best ways to erase grass and explained
-Added example of graphical representation for buttons that remains pressed or for couple of pressure plates that keep their activation after being pressed simultaneously; in the same way plasma doors on pressure plates to signal the option to keep them pressed by themselves; "adding the possibilty to jam a pressure plate"
-Added a simple fan with invisible walls
-grouped the wire tetrominoes, and something else, changed(where useful) the balance wire to a balance path marker (so the item can be logically linked with L without creating useless activation links to wires)

-will add soon squares for guided placements, big invisible floor+explanation

Explained about a rewind-inconsistency problem that can happen with accumulators and provided the solution with an "alternative" design(I won't go in detail here); Thanks to Shlam!

minor thing: added a cluster of window frames(acting like a big window if someone doesn't want the big edges)

Added a plasma barriers that show 2 different names when entering and when going out
added longer timer example made by receivers
changed some QRs, changed info of the level
added an example of 6 shared statuses with any number of switches

added basic things(vertical fan with frames, for items only, added a big window to be used as a floor)

added slightly different design of base recording detection

-added TC, tower counter(to check a certain number of conditions are met without specifying any of them in particular, helpful when conditions are around 5 or higher)
-added 2 kind of doors(letting only the character pass/letting everything but the character pass) by WIll_gamerboi
-improved one design about the switches with a shared effect (removing the cube from under the mine)

fixed a typo, removed a useless link between 2 receivers,
made the interchangable switches work slightly differently(more efficient for a big number of switches)

Made the bichromatic and the inverted version only targetable in their connector(I hope their physical receivers are not targetable even with extreme angles)

added
-common construction section(base bootstrap, only-item fan, only-once switch,monodirectional window)
-relatively simple logic mechanisms(base cycles shown, on/off statueses, short-time actions, same on/off switch effects, interdpendent switches' effect)
-laser setups SPOILER section: showing concepts of clocks, "multi-statuses crossings", synchronization
all of them are still work in progress

to add in the future: ordered counting/sequence checker, disordered counting

made sure the swapper ceiling is high enough, maybe it already was fixed but I have just pushed the update to be sure
Forgot to update the version shown :(

-made the swapper not walkable on the buttons inside(it was an oversight I didn't take into account when I raised the roof)
-added inverted bichromatic/copycat variation (in which the inverted copycat takes the colour of the bichromatic upside receiver(upside instead of sideways... I have to find right names for those)
-minor changes: tweaked a teleport destination to come back easily, added an intermediate anti-cheese button(as a third option)
