Quick Finder is a QGIS plugin as a dockable dialog to quickly find a feature by its ID in a layer or by other attributes.
Quick Finder is a QGIS 2.x plugin. There is not port planned for QGIS 3 since most of its features are already accessible:
You can select, pan, scale and open form for the returned features.
See demo on youtube (this version is 1.0, some features have been added since)
