How to save Chrome tabs for later and bring the whole set back
Short answer
In Chrome alone, press Ctrl+Shift+D (⌘+Shift+D on a Mac) to bookmark every tab in the window into a folder, then right-click the folder and choose to open them all when you need them. With Simmer, put a task on the back burner: its tabs are saved and close, and one click brings the whole set back, in its group.

Four ways to save tabs in Chrome
1. Bookmark all tabs
Press Ctrl+Shift+D (⌘+Shift+D on a Mac), name the folder, and save. Every tab in the current window goes into it. To get them back, right-click the folder in the bookmarks bar or the bookmark manager and open them all. This keeps the set, but each folder is something you name and file yourself, and it's easy to end up with many folders you never open again.
2. Save a tab group
In recent versions of Chrome a tab group can be saved, so it can be closed and reopened later from the start of the bookmarks bar. It keeps the group together, but only for tabs you put in a group by hand.
3. Add to the reading list
Right-click a tab and choose Add tab to reading list. Good for a single article you mean to read; it doesn't keep a set of tabs together.
4. Leave them open
The most common choice, and the reason tab strips get long. Chrome's Memory Saver eases the memory cost, but the clutter stays.
Save a whole task with Simmer
Simmer saves tabs by what they're for, without asking you to file them. It works out the tasks itself, so Kyoto trip holds the hotel, the train timetable and the temple hours together. Putting a task on the back burner saves each tab before it closes, in Simmer's list on your computer and, if you like, in your bookmarks. Nothing is dropped to make room.
To bring it back, open the side panel and press Bring back: every tab reopens together, in its group. To find one tab, search the side panel or type sm and a space in the address bar, which searches open tabs, saved tabs and bookmarks.
Save a tab until a set time
Sometimes a tab only matters later: a sale that starts on Friday, a form you'll fill in on Monday. Simmer can snooze a tab so it closes now and comes back at the time you pick, in its group.
