Been using software to monitor performance of my RV on a recent (ongoing) trip. Here are some suggestions for improvement.
1. Manual scale for real-time graphs. It's disconcerting to have the vertical scale change. I would like to run for a while using the auto mode to establish a reasonable range, then lock the scale to something of my choosing. While it's nice to have one parameter display its current value in a large font, the values for the other parameters are essentially hidden because the scale is variable and the font is too small to read while driving. User-specified scales would eliminate this problem.
2. Meaningful file names for exported data e.g. YYYYMMDD_HHSS.csv. Not sure what information comprises the current file names.
3. User-configurable widget to display the current value of a few selected parameters. I would like this widget to float over top of my GPS program.
4. Ability to report fuel consumption in litres per 100 km (that's the metric standard; km per litre is not used).
5. A parameter to report total fuel consumed OR fuel consumed since last recorded value. I've programmatically converted the fuel consumption per hour into a total fuel value, but I don't really trust the calculation. Would prefer a direct reporting of the fuel consumed value.
6. Continue recording into the current file even when the engine is turned off. Use a manual command to close the file. Currently, I must remember to restart the recording whenever I turn off the engine for a short stop. Perhaps make it selectable in the options which method to use.
IMHO, these suggestions would improve an already-great program!
