[Bug 82428] adept details view usability

[Yuriy Kozlov]

Public bug reported:

Binary package hint: adept

The details view in Adept manager and updater (when you click on
"Details" for a package) has the following issues:

The navigation buttons:
There is a back button, and it is most obvious that this back button takes you back to the list of packages.  However, it is actually there along with the forward button to cycle through previously viewed packages.  This functionality is not particularly useful, and the button is confusing.  The history that these buttons use also doesn't eliminate duplicates, so clicking show details on a package a couple of times, then hitting back doesn't do anything (takes you to the same package, but the screen refreshes)
There is a "Show List" button which actually goes back to the package list.  This button has a blank uninformative icon, and along with the back button is unintuitive to find.  Something like "Back to list of packages" (or a shorter variation) with a back icon would be better.
Also, the three buttons get there own toolbar, which leaves a lot of empty space to the right of them.  If the back/forward buttons get removed, the back to list button should be put elsewhere more space efficient.

The tabs:
"Installed Files" makes no sense for a package that is not installed.  The tab should not be there when there are no files installed.
"Additional Information" shows very little useful information and it seems that maybe it could be put somewhere else, and that tab relabeled "Tags".  This is nitpicking though.
There should be a tab to view the changelog for a package (this is currently in progress afaik).

Action buttons:
"Install" and "Remove" could be in the same place instead of always having one disabled.
There should be buttons for the other actions (reinstall, purge...)

Other bugs:
View > Show Package List is disabled and has a blank icon.
