Description

Improve the loading widget that currently appears when pressing Run NCA. Some improvements include:

• Centralize the widget to the middle of the screen, to make more clear to the user what is happening
• Align better the timing of appearance of the widget. Right now the widget seems to disappear a bit before the results have been processed and the user moves to another tab.

Definition of Done

The requirements for the feature to be complete:

• centralize loading widget (or just make more visible)
• no significant lag between widget disappearance and loading of results!
