Here are a couple of new feature suggestions -- see what you think:
Feature #1 -- Stationary Attachments
If this feature is implemented, attachments attachments made to, oh say the feet or the skull, will remain attached to the feet or the skull rather than migrating to the inner thighs or the rectum. Perhaps this needs to be a checkbox in preferences, because the existing attachment migration behavior has been around so long now that I'm sure there's a lot of LSL code that depends on it.
Feature #2 -- Automatic Ditch Fill
With this feature the many unsightly ditches, trenches and assorted other holes in the ground I see as I teleport around would be filled with a liquid substance of the Linden's choice. Water would be an obvious candidate, but I don't want to inhibit creativity here: lemonade or chocolate milk would work equally well.
