The compact scientific formatter emits its leading digit by adding the
normalized integer mantissa to '0'. Its upper normalization loop stops at
exactly 10, however, so powers of ten use ':' (the character after '9') as
their leading digit. For example, -100.0 becomes -:.000000e+01.
Keep the normalized mantissa below 10. This preserves surrounding values
and renders exact powers with a valid leading digit and adjusted exponent.
It's now possible to save capture, traces, or both by clicking SD card icon
Disabling both options hides SD card icon
Config submenu was added to Storage menu, and all settings were moved there
Existing config remains valid, and default behavior with saving a capture is kept
When long sweep completes, a black line appeared at the bottom of the screen
Also, the same issue occurred even with progress bar turned off
