## Additions

### Option to change the negate character

Issue: #877

The option to negate a query: `foo -bar` e.g. search for all items matching `foo` but not `bar` caused a lot of
confusion. It seems people often use rofi to also add arguments to applications (that start with a -).

To help with this, the negate character (`-`) can be changed, or disabled.


### Modify the DRUN display string

Issue: #858

An often requested option....
