Modes:
* ''download'' remote object, if current object is from remote ''source'' and wasn't downloaded previously
* ''download'' remote object, if current object is from remote ''source'' and wasn't downloaded previously
* ''sync'' current object with remote one, if current object was originally downloaded from remote ''source''
* ''sync'' current object with remote one, if current object was originally downloaded from remote ''source''
* ''delete'' object from local system(i.e. from the Journal), if current object was originally downloaded from remote ''source'' it would turn to "un-downloaded" state

* ''related tags''
** cloud of ''related tags''
** tree (made by ''composite tags'') of ''related tags''
* without any tags i.e. all objects
After proper ''tag'' was chosen:
# selected ''tag' would be added to ''chosen tags'' list
# ''related tags'' would reflect on the final list of objects

User can choose what kinds of tags it should contain:

= Implementation =
Implementation details.
=== Database model ===
Library follows simple rules:
* use local datastore API to search/filter ''local objects''
* use remote datastore API(in some way) to search/filter ''remote objects''
* use telepathy tubes for notifying users about changes
* sync shared objects while opening Library activity or manually
= Going further =
=== Integration with Sugar components ===
* downloaded files by Browse activity
=== Simplify UI usage ===
* several levels of UI complexity
* presets with different sets of UI components
=== Various non-sugar ''sources'' ===
* FTP servers
=== Room/Lesson mode ===
