So you want to have a shopping cart. With drush_mm it's a snap.

drush --verbose mm enable uc_cart

Using verbose output this shows

Given module names: 'uc_cart'
The following modules will be enabled: 'tapir, uc_store, token, workflow_ng, ubrowser, uc_order, uc_product, uc_cart'
Installing modules
Enabling (and mayby installing) module: tapir
Enabling (and mayby installing) module: uc_store
Enabling (and mayby installing) module: token
Enabling (and mayby installing) module: workflow_ng
Enabling (and mayby installing) module: ubrowser

What modules does one need to get faster user experience? This probably leads to using ajax.

One of my thought is some node/%/edit's one one page. Preferably on tabs too!

Just browsing the categories http://drupal.org/project/Modules/category/101 (javascript utilities) and content at http://drupal.org is still overwhelming.

Here is a listing with just some modules.
- http://drupal.org/project/ajaxtable
- http://drupal.org/project/autosave
- http://drupal.org/project/block_refresh
- http://drupal.org/project/compact_forms
- http://drupal.org/project/cck_fieldgroup_tabs

Using drush with a strict server design makes my drupal maintence much more relaxed. I have this tiny script as a runner for drush.

$ cat drush
