FilterReview: features to be implemented

[IamPete1]

Somewhere to note down all the features that we would like:

• More speed! Faster filter calculation would allow auto-re plot.
• Show filter tracking on averaged FFT plots (FilterReview: add notch tracking to FFT plot #11)
• Zero pad FFT data to allow running on batch sizes that are not a power of 2. (also do some reading to check that this is mathematically valid). Some reading suggests that zero padding might be a bad idea Or make the batch length selection box move in powers of 2. (Done this bit) Make windows per batch option take steps such that the window size is a power of 2.
• Add plot with general flight data, (roll, pitch, throttle) to allow selection of "good" portion of flight for FFT (FilterReview: add flight data plot for setting time range of analysis #12)
• Add param descriptions and bitmask helper (possibly auto generated from param meta data) (Layout generation from param metadata #30)
• Add more text to page describing how it works in more detail. (FilterReview: add lots of tool tips #106)
• Add link to filter tool for more detailed look at filter bode plots (FilterReview: add button to open in filter tool #23)
• Support accels?
• Add loading spinner to stop dead page warnings, loading page added does not spin and will not stop dead page warnings. all: add loading overlay for logs #55
• User configurable window overlap? Currently hard coded to 50%
• Highlight the primary sensor.
• Prompt to select estimated post filter if not shown and filter param change is done.
• Option to show logged notch center frequencies (FilterReview: add the ability to plot logged notch frequency on spectogram #108)
• Double check ESC notch source correctly avoids dropouts. There seems to be a bug in AP's logging here, not sure we can tell dropout vs genuine 0 rpm.
• support 4th and 5th IMU
• Warn if lots of missing data
