This is an improved version of default editor gizmo + number of related utilities. It has additional controls – free rotation sphere, screen space rotation arc and translation dual axis extra handles. Also the way delta applied is rewritten to properly handle local space transformations.
In other words, it gives you a number of well known and widely used 3d transformation features everybody got used to! And, thus, brings in editor workflow closer to industry standard.
Transform Tool supports 4.17, 4.18, 4.19, 4.20 engine versions for windows.
