[Suggestion] Add more buttons into the main toolbar

[notuxius]

'Get latest distro news', 'Install local package', 'Open root terminal', 'Cache Cleaner' and 'Repository Editor' buttons can be added to the left side from the 'Find' field.

'(Search)By name', 'By description' and 'By file' buttons can be added to the right side from the 'Find' field.

Such a wide 'Find' field is overkill even with the narrowest main window size and there is enough space for proposed buttons + it will create faster/more efficient workflow.
