Sometimes game freezes when I click on "ADD-ONS" in game menu and I have to kill the L4D2 process. Problem appeared after installation more then 15 different addons. There is no such problem in L4D2 Beta, but I haven't got many addons installed there.

Also can you please fix the position of "Some installed Addons do not support Campaign mode." line in lobby creation menu: http://puu.sh/1PD05

Same here, I can't upload campaign. 500 MB is not enough.
Is any chance that you'll increase Steam Cloud quota in the nearest future?

Campaigns titles are missing in TAB menu.
When campaign contains more than 5 maps, word "Rescue" is shifted to the right. Also there is no such bug in russian version of L4D2.

Also, I suggest to add the numbers next to or on top of each picture that will match the ordinal number of the map. When campaign contains more than 5 maps, it's seems like players have problems with determination of which map they're playing right now.

If an addon has a mission script, then it's considered a campaign addon and will only be loaded when you're playing that campaign.

Gnome's model is replaced in some campaigns and, when I have one of this campaign installed, original gnome in Dark Carnival has collision model of the custom gnome model from last installed campaign: http://puu.sh/1LnGm
Also gnome collision is broken in early installed custom campaigns that replaces gnome model.
So I just intersted why it happens?

More serious problem is caused by custom campaigns that have "soundscapes_manifest.txt" in their VPKs. When another custom campaign with its own soundscapes starts, wrong soundscapes are played on the first map, but after level once changes all soundscapes in current campaign work right.
So one campaign with "soundscapes_manifest.txt" in VPK affects to all other custom campaigns that have their own soundscapes.

For example: http://puu.sh/1Lows
This is from comments to Undead Zone campaign, that have its own soundscapes.

The campaign with "soundscapes_manifest.txt" that I know: Vienna Calling 2, Silent Hill L4D2.

It's not a serious issue at all, but I think it must be reported: http://puu.sh/1Lmg7
In this menu all campaigns titles are replaced by "Dead Line 2".
This problem exists only in "Left 4 Dead 2 Beta" and it's not in "Left 4 Dead 2".
