The features 'insert rows' and 'insert columns' were already fixed in the previous patch but I didn't realize it.^^ The sleeper and light properties required some minor code fixes because they differ from universal block properties (density, damage, id etc.). All blocks have an id but only a few ones have light properties. That's the major difference that caused a bug or incompatibility in the insert and remove functions.
One day I'll rewrite it because it's still buggy and may cause crashes.
Quite the opposite, my buddies say that I should add some trendy feature like hidden bitcoin miners, encryption trojans and other cool stuff. But seriously, feature removal is not going to happen.
Update Time!
Changelog v0.61 (Jan. 4, 2019):
- reactivated insert rows and columns
- changed: pic. for no texture / delete
- fixed: hearing percent in sleeper properties is multiplied by 100 when you use the block picking tool to read the block properties
- known issues (should be fixed in the next update):
- cutting light or sleeper blocks (ctrl + x) changes the values of the light or sleeper properties; Use copy 'n paste (ctrl + c & ctrl + v) until the bug is fixed
- middle mouse button (block picker tool) doesn't work properly. You have to click the middle mouse button twice for it to work.
Btw. the new version can be downloaded directly from the op (if the auto-updater is not working for you) .
