Radiant needs some modifications to make its use even simpler
- Make icon foe 3DMPR alone instead of selecting it from ad drop down menu
- in 3DMPR make the crosshair "Axes" incomplete in the center since it interferes with looking at a specific spot and I have to remove the axis every time I use 3D MPR
- If I take a measurement or ROI near the axis it interferes with the mouse which select the axis instead of painting the ROI which is annoying and have to disable the axis and re-enable it again after I take the measurement, axis should be disabled "become unselectable by the mouse" if a measurement, ROI or annotation tool is selected. (this is in HOROS and Osirix since ages)
- Zooming in a plane in 3DMPR should propagate to the other planes
- The custom keyboard shortcuts should be also the same in 3DPR (in 3DMPR it reverts back to default)

No official reply for that suggestions
that explains a lot, since radiant is abandonware after all
