Blocks Grouped by Type in Control Panel
Any grid should automatically create groups for every Type of block used. These should be invisible in the usual view, but the list should be toggeable to show only these groups.
Also in the toolbar setup make a new category block type groups and add them there.
I have to create these groups manually almost every time. Like with drills. You always want them in a group. Same with thrusters, wheels etc.
PS: thank you for small grid doors!
