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)

-Added a bichromatic receiver (accepts both red and blue) and copycat connector copying that light colour
-Added swapper (like TTP2, made with 2 buttons)
-Added clone mechanisms to give you star/collectibles with a switch or some conditions,
terminating the recording on command
and "changing destination" of the teleport
similarly added showing the puzzle name without plasma barriers in sight
-Added anti-cheese pressure plates (preventing offset positioning and pressing multiple pressure plates at once)
