Suggestions for future versions:
1) Add fuel left in percents
2) Add option to display KMH/MPH/Knots & Meters/Feets within united lines to compactify HUD yet still providing option for those accustomed to one measurement system and wishing to get used to another, or flying non native planes (eg. by landlease)
(eg.: AS:XXX kmh(NTE:700)|YYY mph|ZZZ knots, maybe even +number of 'height values' radio commands tell you to fly at)
3) If possible, add effects highlighting important values:
a) highlight values with red font or even flashing white-red over-exceeding airspeed/overG/over angle of attack;
b) highlight with green when speed is within landing speed range;
c) optionally put after airspeed in parenthesis never to exceed value for easier rememberance/quick glance checkup (not calculateable/changeable value, but might be handy and also is plane specific);
d) highlight with red if supercharger mode needs to be switched up, with blue - if down;
e) highlight fuel mixture if according to current height it needs leaning (red) or richening (blue);
f) blue if rpms are too low, green - cruise rpms, yellow - combat rpms, red - too much
- Drawback for such highlighting (preferably optional of course) (3.) a-b-c-d-e-f might be for it to require setting those values (from readme-s or manuals) for only one specific plane. Asking for that to be set automatically probably is too much, though several commented out lines for most common planes from which needed one can be uncommented might be simple to do.
g) temps might benefit from highlighting as well, but overtemp shouldn't be plane specific
