Map Handling - single vs multiple

[piuggi]

• When any file is selected in a clip, the map disappears, this needs to be modified so that the map only disappears when a file in the first indexed zone
• Need to make decision about single vs multiple. Currently the system doesn't care if its single or multiple and toggles accordingly, it proves that single/multi options are a bit irrelevant to our users therefore we should come up with a better term for that option.
