Hello SiscoArtz, I see you chose to resurrect a very old thread! 😃
Some of the requests in this thread were added to spine, for example you can now paint weights with a brush if you change mode:
Weights - Spine User Guide: Mode
And you can use soft selection as well for general vertex manipulation:
Mesh Tools - Spine User Guide
You can hold ctrl (cmd on Mac) and click or click and drag to select the vertices.
You can use PagUp and PagDown to quickly navigate your previous selections.
Selections can be stored by pressing ctrl+1 (cmd+1 on Mac), where 1 can be any of the number keys, 0-9. The selection can later be recalled by pressing the number key without holding ctrl or cmd.
