Please look at the FAQ as your first source of site information. You can access it by clicking on FAQ at the bottom of every page, or:
The FAQ page has a search option if you don't want to wade through all of the FAQs, and an option to sort so the most recent changes are at the top of each section. That's a good way to stay on top of what's happening with bugs and features before asking here.
Serveral user interface options can be set by clicking on Options in the top navigation bar. New options will be added regularly, so be sure to check it frequently.
Note: The FAQ currently is the prime source for information in bugs, features, already suggested cosmetic changes to the user interface.
Some current features, such as Ignore, Preview and Spell Check are only partially implemented at this time. Similarly, the UI will be very customizable by the user, however, only a limited number of options are available now. Customizable features for entitled users will ultimately include font style and sizes, colors, format and order of lists, number of items in various lists, placement of elements, etc.
