I'm interested in the possibility to add a custom field to the toolbar which would behave similar to fieldtype: filter, except it would execute a custom script on-key-up with the fields text as argument. Such a type could also be declared inside a script addon and appear in the field type menu automatically if any addon exposes such functionality similar to how custom columns are exposed. Having a delay timer built-in would be quite useful as well as to not spam requests while the user is still typing or have to handle it in code.
For now the only way to do something similar is with a dialog which has to be initialized and for obvious reasons can't be a constant part of the toolbar.
Example use cases include:
- A tab filter which would color all tabs if they match the entered text partially or even send them to top (yes I have more than 50 tabs on each side at all times). Hiding specific filtered tabs would require a new command.
- Streaming results from a database and displaying them as a file collection with dummy files
- Rewriting https://resource.dopus.com/t/8894 to be easier and even more transparent to use comes to mind as well.
