most textmate dev nowadays is being done in bundles. while the elastic tabs thing doesn't work quite right in textmate, textmate's tabbing (soft-tabs to convert tabs to spaces, backspace to go back a 'tab', autoindent based on syntax conventions) is pretty satisfactory.

one thing it doesn't do that looks REALLY appealing with elastic tabs is multi-tabbing, especially to appropriate spacing on multiline parameter lists. i'll add 'write a bundle to do this stuff' to the long list of projects that fall behind the startup.
