Extend functionality of search dialog

[dvchristianbors]

Extend the search dialog in the column header by navigational buttons.
By adding a forward and backward button to the search dialog, the user can cycling through all matching search results.

Additionally, highlighting all rows containing the search term could also be beneficial.

User story

When using search, only the first occurrence of the search term is brought up. However, if the search term occurs multiple times, the user cannot cycle through all search results. Especially for columns containing unsorted items, other items matching the search term will not be discovered.
