thanks again for your work !

some suggestions concerning Catorise Gui :

1) this is probably not that important and doesn't affect functionallity or usability, but you may want to fix :

when the user creates a new category, a hildon-style banner shows up telling the user that his category has been created and to click save in order to reload the menu, however the menu still reloads without clicking save.

the user may want to customize the menu and create multiple categories/edit existing ones/re arrange items then reload the menu once he is done.

if hildon automatically reloads the menu once modified, you can circumvent this by creating a new folder some where, create the new directories there, if a user changes a directory make .change file for example describing the changes.

then once the user selects save, move those directory files to the appropriate folder, and apply the changes descried by the .change file, meaning don't actually make any real changes until the user click save, till then keep all changes virtual.

this should prevent redundant reloading of the menu.

2) this is a hard one; you may want to reconsider the arrangement of the UI, instead of having a list of applications with a list box beside each one, you can try a more organised UI, a hildonized alacarte UI perhaps ?
alacarte is coded in python, you may want to take a look.

thanks in advance.
