Split oversized groups

The giant-group splitter is optional. When it is on, Tab Organizer can divide an oversized Chrome tab group into smaller sub-groups during native Tab Groups Sync. It does not split groups only inside the popup list.

This version has no dedicated splitter screenshot. Configure it from settings and verify the result in Chrome's tab strip.

When it runs

Splitting runs while Tab Groups Sync (BETA) is applying group updates. If Sync is off, enabling the splitter stores the preference but does not rewrite native groups until Sync is active.

Sub-groups are named from the parent group plus a domain or title-prefix segment, separated by ·.

Enable the splitter

Steps

1. Open Tab Organizer settings.
2. Expand Giant-Group Splitter.
3. Turn on Enable splitter.
4. Leave Sync off until you have set the threshold and strategy.
5. Enable Tab Groups Sync (BETA) only after you accept its overwrite boundary.

The control is off by default.

Threshold and strategy

Tab threshold is the minimum tab count before a group is split. This version accepts values from 5 through 50. The default is 25.

Split strategy is one of:

Strategy	What it uses
By domain	The registrable domain of each tab
By title prefix	A shared title-prefix segment

Steps

1. Set Tab threshold with the slider or number field.
2. Choose By domain or By title prefix.
3. Enable Sync only when those values match the groups you want split.
4. After sync settles, compare Chrome's tab strip with the extension list.

Verify a split

After a split you should see smaller native groups whose names include the parent label and the domain or prefix segment. If a group stays whole, it may be under the threshold, Sync may be off, or the tabs may not share a strategy key.

Turn the splitter off if you need the original oversized native group back, then re-check assignments before enabling Sync again.
