* Loading Indicator
|
|
*
|
|
* When the user performs an action, it is good to give him some feedback that
|
|
* something is currently happening. The purpose of the Loading Indicator is to
|
|
* display a small rectangle on the bottom right of the screen with just the
|
|
* text 'Loading' and the number of currently running rpcs.
|
|
*
|
|
* After a delay of 3s, if a rpc is still not completed, we also block the UI.
