• Remember waveform compression settings (under Settings > Compression) between LTspice invocations

I find that somewhat troublesome, because simulations won't run the same every time you fire it up.  I like it when you know exactly what you're getting.  While it is true that waveform compression can be more trouble than it's worth, this makes controlling it somewhat random.

 

Note that waveform compression settings are now remembered in version 24.1, for the exact reason of making it consistent every time LTspice opens.  In previous versions, users would sometimes disable waveform compression, only to be surprised to find that it reset to enabled the next time they opened LTspice.  This came up often.  I'll also note that waveform compression can be configured with .options if you need to configure schematics a certain way.  Nowadays, available storage space is sufficient for most simulations, so the motivation for compression is reduced, and problems due to its lossy nature are fairly common.  Better to utilize a temporary directory for raw files, and limit saved signals and/or turn on compression when necessary.
