TabLimiter от LexicusRex

Set soft and hard limits on your open tabs.
The soft limit acts as a gentle reminder and inconvenience to guard against excessive tab creation.
- When your tab count reaches or exceeds the soft limit, a popup window appears allowing you to manage/close tabs you select. You may also continue without managing any tabs.
- When you exceed the hard limit, any subsequent tabs will automatically close, and the popup window will show.
The tabs are sorted in a grid from least used to most recently used. Users can hold SHIFT to bulk select multiple tabs in succession or CTRL to select specific ones.
