Align World: process only coincident UV loops per vert for a more accurate and predictable result removed simple and recursal modes.Randomize: Within Image Bounds now takes into account strenght values and rotation.The created UV Mesh will inherit the origin location from the original mesh, instead of being placed in the global origin. Most of the original mesh data is now preserved. Create UV Mesh: it now works on the whole object or the selected UVs.Tuned detection of lines in Rectify, triangular faces and ngons are discarded now.

Rectify: recovered align verts, edges.Align: Fix weird behaviour with partial selections while in Face UV Selection Mode made it to work on the selected faces only.Added support for multi-object UV editing. Straighten: any chained sequence of edges is supported, not only edge loops.Unwrap: new custom operator to unwrap only selected UVs, with the capacity to constrain the operation to the U or V axis ( BenjaminSauder).Relax: added new utility for UV vertices smoothing.

Basically it should be possible now to use any utility of this addon with high-poly meshes.

Massive performance gains in Rectify, Straight, Edge Peel, Select Bounds, Create UV Mesh, Randomize, Align World, Align Sort, Select Similar, Texel Density Get and Texel Density Set, among others ( from x2 to 10000x).
