Linden Lab have announced that CHUI is now part of the main viewer and will appear either by automatic update or when people update to the latest release of the main viewer. This is likely to be a Marmite issue for many, with people loving or hating it, although for me, I sort of like it, unlike Marmite, which should be illegal.
CHUI (Communication Hub User Interface) has pro’s and cons, one of the cons is that it takes up a lot of screen real estate. This is fine when you’re chatting away but when you’re roleplaying or getting immersive, it gets in the way and when you minimise it, you can easily lose track of what messages are arriving, although over time you’ll get used to it.
I’ve been using CHUI for quite some time, first in the form of the project viewer and then in the form of it being incorporated in the beta viewer. Over that time it has undoubtedly been improved, the issue with local chat not staying undocked being one major improvement, but there are issues with it that I still find irksome.
There are some good pro’s with it, the way you can view chat history being a really big improvement, no longer do you need to search through your hard drive for those old chat logs, once you’ve im’d someone, the viewer allows you to view a chat history. I’m not sure why you need to im someone for this to work, once im’d the setting sticks, you don’t need to im them again to view chat history.
