Ask HN: Viable supported replacement for Tab Sugar for Chrome?

The development of this extension is being discontinued both because it reached Chrome's API limitations and because of my lack of time. Hi, I decided recently that I'd like a tool to group tabs together, be able to close them and then come back to them. This way I wouldn't need to keep 50 bajillion tabs open and having this facility would allow me to compartmentalize my online activities. I did a search for chrome+extension+tab+groups and stumbled upon Tab Sugar but it seems to be EOL'd. Can somebody recommend something or should I try this out? Thx!
