After practical use of this great Tool - i can confidently say: It makes me happy !!!
I already adapted my main prefabs and reworked the rest for my mod. (yes, i make custom prefabs but I don't share them because they are not compatible with vanilla)
I haven't had time to read other feedbacks...maybe i'm repeating, but, here are two things that caught my eye immediately and stay remember:
1 - during work constantly need to know which block to be under the cursor, for this purpose have always move a sight at the status window (upper left corner, small font, etc)..it's a long way... I would like to see this important information closer. For example, as a tooltip under the mouse (if it will appear immediately) or large inscription which is close to the main work area to see her peripheral vision...
2 - Lacking "Load Recent List"
Big THANKS for this Tool !
