The Habitats software is a great little editor and it is awesome to be able to plan and visualize your terrain build before printing everything out.  I would like to recommend a couple of QoL enhancements that hopefully you can add in the next few releases.

For the shapes menu it would be great if a user could do these two thing:

1. Pin the menu so it always stays open.  This would be great so if I want to see how different pieces would fit and look, I don't have to keep clicking on the folder icon to reopen the menu.

2. Filter the menu by terrain projects so if I want to focus on just a couple I don't have to keep scrolling up and down to find the other project.

I'm loving the editor so far and look forward to seeing what features you add in the future.  Adding color to the hexes maybe?
