First, I have to say I love the tool and I have found only one issue. I have already sent feedback about this, but since it´s not fixed I’ll give more pressure and write my idea to all.
IP filtering is very frustrating, I mean not so easy and quick thing to do especially when we could have about 50-100 address to filter and 500 character limit is going to be also issue for us. Couldn’t you just make X amount of fields (like in Excel) and to those we could copy & paste our IP-addresses and forget those regular expressions (don’t forget, but as default I don’t want to use those). So like this:
Add IP to filter:
+ Click this and add new ip to filter.
Or easier and faster way would be just to import .csv file with all the ip addresses and Optimizely could automatically add those to IP filtering. And make it possible to add at least 100-200 IP-addresses to exclude.
