From the blueprint widget editor, it is not possible to have all the nodes in the palette, you would need another palette to be able to browse all the blueprint functions.

Maybe with the possibility to see the nodes available for the targeted blueprint class.

For example the nodes under Editor SubSystem are missing.

Allow to display the nodes in the palette in the context of the input output selector , and to browse them in the palette in addition to the menu context.

At the moment it is not possible to create brush geometry with blueprint, this is a pity because you could create complex objects without using pocedural mesh.

It lacks the possibility to create a static mesh from the procedural mesh without going through the detail tab, you have to be able to use a function to create automations.

To allow to see all the functions and events from a palette for a class blueprint, and to be able to classify the parent and child functions.

See all the dependencies of a blueprint directly in the blueprint editor and be able to go up the functions of the various classes.

Add an option to compartmentalize functions and macros in the editor domain.

Add an option for the sphere trace result which allows to know the vertex(s) to touch, which could allow to paint with the blueprint the vertex(s).

Then, add a function that allows to paint vertex directly from the blueprint to create automations.
