Any Alternative to Slide in Panels that does not compromise UX?

We are in the process of developing an Enterprise level Web Application where certain screens have cards housing some information on them and are clickable. Upon click instead of a Modal we have currently incorporated a slide in from left pane in which further information and edit functions are provided for the user to play with.

We were thinking of a different way to showcase and provide the same information rather than the current slide in panels style because it has been long used by us and feels old and out of the era.

Just wanted to know if there are any healthy alternatives which don't compromise on the UX and the Look [UI].

Thanks & Regards Mel
