Rename some components and improve the project's structure

[AlbertoPdRF]

Is your feature request related to a problem? Please describe.

There are some components whose names are not very clear in regards to what they are for. For instance, EventSteps or UserTabs come to my mind.

Also, the project's structure is quite plain at the moment.

Describe the solution you'd like

The misleading components should be renamed to make it more clear what they are for.

Also, we should think about the project's structure and, if we find a better one, change it.

Describe alternatives you've considered

Leave everything as is.

Additional context

None.
