Description of the need
There should be better integration between the module list and Installer module for missing modules. Currently if a module like Ubercart is missing a dependency (like Rules), there is a note, hidden in the "more..." details element. User would need to search and download that missing module, which seems unnecessarily complicated if we have an Installer.
Proposed solutions
- have the "Rules (missing)" span be a link, or create a new link that adds the missing Rules to the Installer queue in the background
- have a dropbutton in the operations column that says something like "Add missing module to install queue" which does that
- have a filter checkbox/button in the installer that filters the Installers list to only missing modules. Link to that either from the previously mentioned dropbutton or details span
Example
Example of suggestion 1 above, but this looks cumbersome.
