The modules page is already quite long with only the core modules but when you add views, cck and other modules you're going to use on your project it becomes unwieldy. I've created a little proof-of-concept module that turns the fieldsets on this page into tabs.
Dependency: http://drupal.org/project/jquery_ui and you need to download http://code.google.com/p/jquery-ui/downloads/list?can=3&q=1.6 unpack it in the jquery_ui directory and rename it to jquery.ui.
Entering passwords on a mobile phone is a pain since I'm never sure if I entered the correct letter. Now it seems that the standard password field is more of a pain than I thought. Jakob Nielsen tells everything in his alertbox: http://www.useit.com/alertbox/passwords.html
Usability suffers when users type in passwords and the only feedback they get is a row of bullets. Typically, masking passwords doesn't even increase security, but it does cost you business due to login failures.
When a client needs changes to his Drupal site I always ask a recent DB dump and the files they use in production. With this files bundle comes the files directory which usually contains the imagecache directories. With this last client that files directory was more than 6G and that was impractical to copy.
At the the drupal.be code sprint I worked on a module to download Drupal and accompanying translations and make that package available for download. This functionality has turned into the packager module with some extras. It is now also possible to make the package download modules and include them in your download. This makes it interesting to set this up on a local Drupal install so that you have your own Drupal distro with your most often used languages and modules.
On valentine's day I attended my first real code sprint, the drupal.be code sprint. I was really looking forward spending the day with a bunch of fellow Drupal enthusiasts to implement the new drupal.be.
