Couple things, FYI:
All carved tops are now DL tops. This means they require binding.
Also, by way of information, here is the current situation with the visual-style builders: They are overwhelming to maintain. We know they are super cool, but we have created a monster that always wants to be fed. The builders in their current state are unsustainable.
Here's what our plans for the future are: we are working on a completely new website, rebuilt from the ground up. In the first iteration of this new site the visual builders will be going away. We are fully prepared for weeping, wailing, and gnashing of teeth, but it has to happen.
We want to urge everyone to prepare now for these changes. A 3 month supply of food and water is recommended. In situations such as these precious metals, in the form of bullion, will be the only real money. Honey, cigarettes, and ammo can also serve as currency. A 72-hour survival kit, stored in a backpack, will allow you maximum mobility. Other helpful items: rain barrels, water purification tablets, penicillin, pencil and paper, first-aid kit, flint and steel, toilet paper. Begin keeping a diary, so that our children may remember the past. Oh...and batteries. Lots of batteries.
These changes are still a long ways away...many, many months. A simpler and easier to maintain version of the visual builder will be priority #1 after the new site is launched.
