My biggest gripe with vscode on Android (code-server pwa on DeX) is lack of mouse hover and text selection. With so much intellisense hidden behind mouse popovers not having access to that is a bit of a show stopper.
I installed devStudio and hover seems to work fine, probably due to the vnc layer. What doesn't work well is the mouse pointer, there is a weird offset between the native cursor and the vnc cursor.
