It's a ritual.
I've used Gmail as my primary mail client since it was first available in 2004, and it just keeps getting better. I love it's simplicity, and the way Google has been rolling new features into it over time rather than a big "upgrade" or "redesign" as I've witnessed and experienced in other products.
I like the subtle changes and there's a feeling of 'delight' that this type of staggered (i.e.: Agile) feature roll out approach offers for the user. It also makes it possible for the developers to really focus on the implementation and get feedback early and often to squash any bugs and resolve any unforeseen front-end glitches more effectively as well. With this approach, everybody wins.
It's Delightful & Delicious
Today I had a pleasant surprise when I noticed some minor, yet really nice improvements in the way that Gmail presents their Tool-tip (a.k.a.: "HoverCard" information). These are admittedly not Earth-shattering changes, but they were a nice surprise nonetheless, so I thought I'd blog about it to see if other folks are also seeing these changes in their Gmail client.
Hover Info; Chat Column
The presentation of info is much better when you hover over a user's name in the chat column — much cleaner and more like a business card where the order of elements is better organized, and the buttons are placed on the bottom of the card. I really like this because the structure makes more sense, and it feels more natural to me.
Hover Over Sender Info
The other improvement I noticed isn't a huge change, but it is better in my opinion. When you hover over the sender's name you get the same presentation, treatment and structure as you do with the user's name. Same look, same feel, same structure: buttons on the bottom. I'm a big fan of consistency and this is also important in terms of usability.
If you're not using Gmail, I suggest you take a look at it and consider doing so. If you are using Gmail already, then I also think it's a good idea to check the Google Labs section every now and then or subscribe to the Official Gmail Blog RSS feed to find out if there's anything new you might want to try.
