Just a quick note . . . I wanted to mention that as a website designer in the US, we have what is known as ADA Compliance (The Americans with Disabilities Act). The ADA Act was passed to protect those individuals with disabilities and to see that accomodations are made in all areas of life (from physical sidewalks to most recently software development and website design) . . . and while lawful compliance of the later areas are still being written, it is always best practice to see that adjustments are made to ease the complexity of use with software and websites. I might suggest that additional length be added to the Tabble pop-up messages (or add the ability for the user to self-adjust the length to suit their personal needs). Also, perhaps additional ways to increase font and/or bubble sizes. Care should be taken to accomodate those who are color-blind as well.
. . . just a thought. Thanks.
