[supersunsett]

Is your feature request related to a problem? Please describe.

1. Can't resize the widget to 2x2 (3-width max).
2. The long prompt "No entries found that match your criteria" is distracting.

Describe the solution you'd like

1. Let it be small
2. Replace with shorter "No entries.", "Nothing here.", or similar
