#### continuum options
Hide output if no save has been performed recently
(otherwise, show the continuum save interval)
Set the output mode. Options are:
- **countdown**: Show a T- countdown to the next save (default)
- **time**: Show the time since the last save
- **alert**: Hide output if no save has been performed recently
- **interval**: Show the continuum save interval
```bash
set -g @dracula-continuum-mode alert
set -g @dracula-continuum-mode countdown
```
Show the time since the last continuum save
```bash
set -g @dracula-continuum-mode time
```
In alert mode, show if a the last save was performed less then one minute ago (default is 15 seconds)
Show if the last save was performed less than 60 seconds ago (default threshold is 15 seconds)
```bash
set -g @dracula-continuum-time-threshold 60
