- //
- // Things to do:
- //
- // (1) Validate memory statistics against OS20MEMU. VMEM11 does it right.
- //
- // (2) Provide an item to serve as a button to cause a secondary
- // drive status window to be displayed.
- //
- // (3) Make file system name display optional.
- //
- // (4) Make drive percentage utilization available as an option.
- //
- // (5) Provide colored highlights for different levels, configurable
- // by item.
- //
- // (6) Figure out why E dies when entering its Type dialog while MEMSIZE
- // or CLOCK is running.
