Several seeds open at once

You can have several seeds open together, each in its own tab below the top bar — the same way a text editor holds several open files. Click a tab to switch to it; each tab keeps its own chords, settings and last render independently.

A tab shows the seed's file name, or Untitled for one you haven't saved yet. A small dot appears on a tab whose seed has unsaved edits, so you can see at a glance what still needs saving. The Close button on a tab closes it; the app never sits empty, so closing the last tab drops a fresh blank seed in its place.
