This was message from Tomek who is creator of Unlimiter v0.5
After combine with unlimiter source code after long days I release unlimiter with new version 0.5.0
* Select manually block variations (only air, ground or back to default automatic selection)
* Build a track with hidden blocks like Quay on Coast, Hidden Tunnels on Island and many more!
* You can turn off creating block clips when in some situations helps
* You can save a block variation after remove a block without any problems!
I recommend to edit tracks in WINDOWED MODE due to displaying message boxes after successful shortcut combine
You can disable displaying message boxes in config and play in fullscreen mode
Shortcuts works only when you have selected a block!
Left Shift = Change a block variation (automatic choose, only air, only ground)
Q + Left Shift = Changes a block "repairing" after removing a other block near it
E + Left Shift = Changes creating clips blocks
Right Shift = Displays a informations about a block (only works when you have DisplayMessages enabled!). Function searches a block under current block selected!
