Viewport tools for saving your time!

ADDON MANAGER

Easy access to addons; easily enable the addons you need and disable the ones you don't need.
When you install a new addon or open the file for the first time, you should press the refresh button.

COLORFUL SELECTION

When you're working on large scenes, make it easy by assigning specific colors to selected objects.

To use this feature, you must set the Color property to "Object" from the Viewport Shading menu.

p

ISOLATE MESH

Isolate just the area you want to work with. When you switch to object mode,

the scene will automatically revert to its original state.

(Alt + T for menu.)

ISOLATE OBJECTS

In Object mode, you can isolate the objects you want while working in complex scenes.

(Alt + T for menu.)

COLLECTION OUTLINER 

Expand the Outliner to show the selected object.

HIDE TOOL 

Automatically hide objects like camera light etc.

The Unhide function does not make all hidden objects visible, it's returns the scene to its original state.

SET VIEW TO FACE NORMAL 

Set view to face normal.

(Alt + T for menu.)

SET SCENE AS DEFAULT

Save your scene as default, don't mess with the visibility settings of the same objects over and over.

CURSOR TO SELECTED

Automatically move the cursor to the selected object with the combination of "ALT" + "RIGHT MOUSE CLICK".

ORGANIZE PARENT

Get together a parent's children in the same place.

Limitations

+ Set view to face normal function does not work when isolate mesh function is active.

+ The "set scene as default" function only affects the visibility of the objects, as the blender python api does not give access to the local collection visibility.

+ It is recommended that you do not change the names of the objects when using the Isolate Object or Isolate Mesh functions.
