When I open a 4D fMRI image (gzipped nifti) all data seems to be loaded into memory before anything is displayed. Even if I never intent to look at anything but a few volumes, or a single voxel's timeseries. This causes significant startup delays even for modestly sized dataset, and make it a challenge to open large highres dataset at all (e.g. 2-3GB timeseries).

It would be great if data is only loaded when it is needed. For example, only the first volume at startup, or a column/row for profile plotting.
