[Bug 1192081] Re: Previews for applications are really slow to display anything

 

I think a small improvement would be at least show some feedback to
click action. I've been using Application lens for a long time, and I
always think I'm doing something wrong when I click on a result.

When I do a search for a given app name and click on a resulting app,
nothing happens for a while. The software is doing some initialization
under the hood or searching online for more info about that app. It will
take 2~4 seconds, leaving me stuck into search results.

If the desired/expected action is to open the details panel for that
app, then at least a 'loading' animation will help to indicate that I've
done the right thing clicking the icon, or open the panel and let it
empty on screen until the app data arrives.

The feel I have using the application lens is that I'm searching for
apps, looking for results, but the "install/open details" feature is not
implemented yet.

Bug description:
  I'm seeing rightly on forums and generally the Internet that 100scopes
  previews are slow, combined with the fact that we now have the left
  click showing the preview by default frustrate a lot of users.

  On my beefy machine (i7, 8G of rams), the preview for an application
  takes 3/4s to show, you can't do anything meanwhile as there is no
  button to launch the application (because you didn't double click,
  just left click and thought "argh, I should have double click").

  Because of this, we are making the 1st landing of 100 scopes
  experience bad and we should fix it (at least, in that applicatoin
  lens) by either preloading the software-center-dbus (/usr/share
  /software-center/software-center-dbus) daemon (we can't have it always
  running as it's taking over 100MB of memory) when hovering an app lens
  result, or when it's the first result (so can be directly triggered by
  pressing [Enter])
