Whenever i do something like a roof or a wall that is similar, like my latest build an aztec temple i built one side and wanted to copy it for the other 3 sides as well as they will basically look identical. But going into the menu EACH AND EVERY TIME i want to rotate my schematic is just frustrating. Either im blind and didn't find this or this is a nobrainer implementation which im guessing would not be too difficult to add.

The 1.21 versions have added these hotkeys (for placement rotation and mirroring). The 1.12.2 dev builds have also had rotation hotkeys (CW and CCW) for a long time, but there is no mirroring hotkey there yet.

Thanks for the reply, but where can I find the mythical 1.21 version of litematica?
