Okay, I tried this, but it's not working for me. Here's what I did and what
happened:
1) I renamed ~/.trinity/share/apps/kate to ~/.trinity/share/apps/kate~
2) I started kate (using its icon), then closed it.
kate created a new apps directory, with an empty sessions subdirectory.
3) I restarted kate and it still shows the sidebar with the file names.
4) I tried creating and saving a dummy file to make kate create a session, but
its sessions subdirectory remains empty. :-(

After a little experimenting I found this workaround:
1) Start with pristine kate config dir
cp ~/.trinity/share/apps/kate{,orig}
2) Open kate with no arguments and close it
3) Open ~/.trinity/share/apps/kate/sessions/default.session with an editor
and change these options to "false" and save file.
Kate-MDI-Sidebar-Visible=false
Kate-MDI-ToolView-kate_filelist-Visible=false
4) Next time you open kate it will neither show the side bar nor the
document list.
