Add a thumbnail toggle for clipboard entriesAdd a thumbnail toggle for clipboard entries

[AiurArtanis]

I would like to request an option that allows clipboard entries to be displayed in a uniform list format, where each entry occupies a box of the same height — similar to the layout used by Ditto. Currently, the height of each entry box is determined by its content (e.g., number of text lines or image height). Adding a toggle for this behavior would make the interface more consistent and visually streamlined for users who prefer a fixed-size grid layout.

Thank you for your great work on CopyQ !
