Feature's intention was tweaked, now it is: Integrate 0install related UI
improvements into shell to have smooth support of Sugar Services[1].

I think having such integration in next glucose will be useful because
it brings "offline" mode for users that have poor internet connection.

== Detailed Description ==

Usage of [[Activity_Team/Services|Sugar Services]] brings 0install
related workflows. This feature proposal supposed to minify
disadvantages and make 0install integration smooth.

=== New widgets for launcher window ===

If activity has pending downloads, Launcher window should have
additional components.

* downloading progress bar
* expander box to show 0install verbose messages
* user could be asked for signed downloads confirmation, text label with
* buttons Yes/No

=== Support offline mode ===

* after uploading 0depend activities to Journal or adding 0install
* packages, immediately start downloading all necessary files
* having, if necessary, "Download all dependencies" in content menu for
* 0depend activities and 0install packages
* having "Download all dependencies" in control panel component
* on downloading activities from Journal(copy to non-ds sources, send to
* other users etc.) suggest/do to bundle all dependencies to downloaded
* activity bundle
* [http://0install.net/0share.html 0share] integration

=== Control panel component ===

* ''0store manage'' like interface to manage zero components
* "Download all dependencies" button
* settings
** network usage mode
*** offline, use only already downloaded files
*** minimal, do not try download last versions
*** full, check and download last versions
** download dependencies immediately
** ignore/ask/do about including 0install files to downloaded from
Journal activity bundles
** on/off 0share
* list of trusted keys

== UI Design ==

* progress bar for launcher window to download dependencies
* new control panel component [[#Control panel component]]
