Feature Request - more intelligence for default save/render folders

If I create a new montage, and go to save it with FILE–>SAVE AS

There is a certain control on this there:

If I am working in a montage, and I click RENDER, the render dialog opens. The suggested folder in the dialog is not the folder where the montage file is located. Instead

The 2 buttons on the right side of the path edit field, should help.
