Sidebar unnecessarily eats half of the screen

[l0co@…]

With my default plugin installation, sidebar takes the half of the screen, while I use it only for 1-2 rows content. Below the sidebar we have a big white area, and the ticket content, extending for many pages, is squeezed to the half of the screen for whole ticket.

I currently modified styles for myself to have the sidebar below the ticket, because with the above it's a bad look&feel for me.

The best solution would be to put the sidebar content, as the "sidebar" only of yellow box of ticket summary, but for 30% of width max. All comments below should be positioned like without sidebar
