I've added support for holes inside the soft rounded Blob objects, you just draw another curve inside the first one, like Slabs.
Also at Funken's suggestion I've taken another look at Blob creation and managed to massively improve the quality around the edges and on fine details. This should make the BLob more useful in general sculpting.
The orange lines were all that was drawn, and Curvy made the 3D mesh from the sketched lines.
The Cloud and Arrow used the Bevel Slider to adjust the maximum height of their Blobs, giving a flatter look. The Heart and Bow used "Lathe Symmetry" to create the mirrored sides from just half the outline curve.
