it would be absolutely fabulous to be able to press F5 and have multiple input objects reload at once; e.g. all the objects below of what is currently selected in the pipeline or those that are currently selected.
Right now I need to go through all input objects one by one.
This feature is not going to be a game-changer, but it would enhance the user experience, for example when debugging a code through visual inspection of the results it produces.
As @wascott pointed out, when selecting multiple input objects, these can indeed be reloaded at once by pressing F5.
What I really want is to have F5 reload all the input objects in the current selection even if that includes non-reloadable non-input objects.
The above update was wrong, I just tested it again. When selecting multiple items, only the last selected item is reloaded.
So, with multiple input objects one is obliged to reload them one by one.
