+1 for text only while pinned
Meanwhile, Windows has a huge range of suitable and creative symbols / text icons that can be used via [Win]+ [.] or via fonts such as
Segoe UI Symbols. In this way, every user can simply bypass the icons specified by the skin developer and individualise them as desired or, if they don't need any icons at all, save space without unpinning the tabs. I would love this option being added.
