I liked this CMS, but I think it lacks the following features:
1. module or content filtering in the "content management" by content type or by any additional attributes.
2. The control panel should display information about users on the site.
3. Blog module must be able to sort by date, attendance, popularity, name. (As in DLE engine)

1. Ок. Now I see that this feature is implemented. I misled the wrong translation to Russian (instead of Filter written Search).

But also I spoke about filtering by addon attribute (not implemented now). If I have thousand modules than I can search necessary module a long time. If when creating a module we can specify a module belonging to definite group. Than we can filter by it. (This features is implemented in blog module. When creating a news we can add several themes for it.)

instead of filter written search

2. Under the control panel I understand the administration panel (where site settings is located)

I understand that we can add statistic module on page with visibility limitations but in my opinion with information must be available in administration panel. Site statistic can include not only users count but also total page number, number of modules/content, content in moderation and so on.

3. DLE - DataLife Engine - it is news CMS developed by russian programers.

You can see it at demo site (login and password: demo): http://demo.dle-news.ru/

I gave the link only as an example implementation of the blog. With regard to categorization of content, here everyone has to decide himself. But I agree that we can found a necessary module via page managment
