This allows for things like related COUNTs and such:

```php
ThreadEntry::objects()->annotate(
    'attachment_count'=>Aggregate::COUNT('attachments')
    )
    ->filter(array('attachments__type__contains'=>'image/'))
    ->filter(array('attachment_count__gt'=>0));
```
This would find all thread entries with at least one image attached.

Move the attachments to the sidebar, add the concept of language-specific
attachments. Add a sidebar to the front page. De-emphasize the "open new
ticket" button. Add a knowledge base search feature to front page and also
add the concept of "featured" articles and categories on the front page.

Ensure that for a model class name and primary key, there is only one object
floating around in PHP runtime. In doing so, ensure that models loaded from
the database are not duplicated in memory. Instead, check the cache when
creating objects to see if the object has already been loaded. If so, use
the loaded model rather than a new instance. This ensures that updates to a
model object are reflected consistently.

Also, short circuit lookups so that the cached version is retrieved without
consulting the database.

For instance
join table2 on (field = 'T' and table1.field_id = table2.id)

Implement select_related() for querysets. Now, related models are loaded
along with the requested models automatically.

Also complete the translation client-side

This reworks the tabs CSS and javascript coding to be more flexible and to
support vertical tabs. (Bootstrap calls this stacked.) The javascript also
allows the URL to include the hash-tag of the last-clicked tab so that the
tab can be automatically shown when the page is reloaded.

Including language-specific attachments

That way, the format can be standardized and the code can be reused among
other translatable objects such as the knowledge base.

Store a complex text with title and body combined with ASCII 0x04 byte
(field seprator).

This will help if the user has "Browser Preference" selected as the
preferred language. When email correspondence needs to be sent to the user,
the browser_lang extra attribute can be used as a backup to to the user's
language preference in the event that the language preference is set to auto
(Browser Preference).

to indicate the primary language expected for translatable content

Drafts 2.0 — Draft system revisited

The solution is simple: upload the image, create the draft automatically,
attach the image to the draft, return the draft_id to the client. That's it.
There's no more need to create the draft in advance now.
