Please re-add a way to select levels by typing in the rank and level number as it was possible in V1.43. The current system is very nice if you just want to play a pack, but it is a lot slower than just typing in four digits.
Let's compare a few ways to select level 8 of rank 5:
a) If you do all the selection in the level selection menu, you first have to press the "next rank" hotkey four times. But these key presses have to be spaced apart by ~1second due to the fading period between the rank pages. Then one has to press 7 times the "next level" key. Because one can easily miscount the key presses, one always has to check whether one really has selected the correct level.
b) A little bit faster is selecting the rank from the main menu: One still has to press 11 arrow keys, but at least one doesn't have to wait for the fading. But selecting the rank in the main menu and the level in the level selection menu is kind of an unnatural workflow. I always forget that this is the faster method when I want to select a new level.
Compared to that, entering 4 digits is a lot faster and much less error-prone.
