Better Searchexperience for Wads

[FreaKzero]

Flow:

• Search in Textinput field
• After the debounce/ordering the first wad gets selected
• now you can control with arrows or WASD a package in the list
• hit enter to select
• clear Textfield

Nice to have: when Filterinput is given, show an x (click) and clear the current Filterinput
