It would be nice, if the open editors could be classified, so that they don't show all the same files.

For example the editor is splitted into 4 parts, now all showing the same source. All editors are numbered.
On close coupled sources like .h and .c it would be nice to add some kind of dynamic filter: Context operation on editor #1 - this editor is "header-editor" for editor #3.

Then the following happens:

• the filelist of editor #1 is filtered to show only .h
• the filelist of editor #3 is filtered to show only .c
• when editor #1 is active and the cursor is inside a class declaration, editor #3 loads the source-file, that shows the definitions for that class
  Really great would be the context-linking, that editor #3 shows the definition for the function, the cursor is on editor #1
• same should work, if edtior #3 is active. Whatever source is shown, editor #1 should load the file containing the appropriate declaration.

If other filetypes exists, that are similarly close coupled that .h and .c - the filter should work there too.
