I need same workspaces for different projects.

Sorry but I'm afraid that's impossible.
As you've probably noticed, there are 2 kinds of settings in our tools: project preferences and global preferences. Project preferences influence the current project only while global ones are set up for all new projects. Since workspaces are listed under project preferences, they need to be adjusted for each of your new projects.
The good thing is that you can easily copy/paste workspaces between different projects. Here is how to do it:
1. Open the 'Manage Workspaces' menu in 'Preferences -> Manage Workspaces'
2. Select the workspace you want to export and click 'Copy' on the toolbar above
3. Open a project to which you want to import the workspace and click 'Preferences -> Manage Workspaces -> Paste'.
That's the only solution at the moment.
