Make more efficient object collections and cell format operations in VBA
VBA Excel user objects are so slow, that i have to mimic it with my own procedures managing user data types, and it speeds up a process by times! Fix it somewhen, please!
Similar situation with cell formatting. Why it's so slow? And more of it - I just can't copy/paste the pattern of different formatting on several cells at once? and some time ago had to spend a lot of tyme to resolve this problem with optimization tricks in VBA/
