Creating Particle Systems is not very straight forward, even though all the needed components are in place by just adding a Particle system, which is good. After that there are quite many manual steps:

• Why adding texture component manually is needed? It would be more intuitive just to drag texture/model to sprite emitter and then the Texture is added or it should be there automatically
• Why user need to go to Sprite particle properties and set texture? Texture that is added to Sprite particle should be set automatically. Later it is easy to change from properties
• Why user need to select Particle in Emitter Properties and then set SpriteParticle?

In general, when user creates the particle system, all automatically added components should be automatically in use in properties and thus working immediately.

All that user should need to do is to add sprite image/ model to SpriteParticle and then have a working sprite system which to edit and modify as needed.
