I use Task Up for the same thing, it’s still maintained. It’s seems like it’s more basic than dash to panel, but it fits my needs.

• https://extensions.gnome.org/extension/6556/task-up/
• https://github.com/fthx/task-up

Just if Dash To Panel became unmaintaned (and breaks with a future Gnome update, as complex extensions usually), there is already a basic replacement.

It’s so unfortunate how gnome is designed the way it is where extensions break and need a lot of work with new versions. I really hope that the devs would take a different approach than this one day. This dev is probably fed up with it and needs a break.
