I would like to know if it is possible to avoid defining a time resolution in the view preset and avoid that events "snap" to the closest time resolution tick when dropping them.
Or does the only possible option consist in using a tiny time resolution, such as 1 second or less?
Sure, but in my case, I simply don't care (and don't want to care) about time resolutions.
I was wondering if it would be possible to avoid having to configure any sort of time resolution at all.
There should be some default behaviour, and possibly it won't be exactly that your use case is expecting. I guess you'll be needed to configure it to make it work as you expected.
