Cinnamon window preview

[desperados]

I've tried Rosa and Betsy, in Rosa I see window preview when hovering with mouse on panel, in Betsy no
is there some option I've to set?

Maybe try this, click on system settings, then click on windows, at the top, click on alt-tab, then see what the first setting says, mine says icons and thumbnails, and i get the window preview on the panel. But there are other settings as well, one that says icons and window preview, maybe this is what you are looking for.

No, the OP means the previews by hovering the Windows List. I don't use LMDE, but I would be surprised, if in LMDE Cinnamon would not offer this. You find the option in the configuration settings of the applet; at least in the main edition it is on by default.

Cinnamon Setting Center --> Applets --> windows list --> Configure --> Check the last option about windows visualization.

Sorry, I did not understand.
