Media Bay - Audio Prop / Image


I tried again the Audio propreties - Image in the Media Bay with N12 and new computer.
It’s still not usable for me. How are you guys using it ?
Display is so slow to come that it is faster to go through your results and look at waveform in the preview window.
I understand it takes time to “calculate” an image so it can be displayed but once done why aren’t they stored in a database like .peak in nuendo’s session so it doesn’t have to be calculated each time you open a folder or change filter in media bay ?
