Version 1.0.6:
- Blender 2.80 support.
- Bug fix.
Note: For better usability; 'Pack together' and 'Align UV Island' work only when UV sync is turned off.
----------------------------------------------------------------------------------------------------------
Version 1.0.5:
- Performance improvement for 'Pack together'.
Note: If you get an error that says 'ZeroDivisionError: division by zero' then please check if you have any UV islands that are zero in size ; they appear as a dot in the UV editor - Usually these islands are created when you unwrap you object then you add some geometry to the object.
----------------------------------------------------------------------------------------------------------
Version 1.0.4:
- Bug fix.
----------------------------------------------------------------------------------------------------------
Version 1.0.3:
What's New:
- Pack UV islands while maintaining their size.
This feature allows you to Pack UV islands together while maintaining their size, useful when you have many small islands and you want to pack them but at the same time you don't want to re-scale (Average islands scale) all the islands again - similar to 'Pack together' in 3ds Max.
How to use this function:

(Make sure that 'UV and edit mode selection sync' is turned On)
Note: it may take from seconds to minutes to pack the islands depending on the number of UV islands you have selected.

Version 1.0.2:
What's New:
- Hard edges from UV islands.
This feature allows you to mark edges as 'Sharp' based on the boundaries of the selected UV islands - similar to 'Smoothing groups from UV shell' in 3ds Max.
