I am using QGIS 3.

I know that i can right click the layer and check the "show feature" option but is it possible to show enable this function by default when any layer is loaded ?

I know that we can set the project. I am looking for option to show it all time. a plugin for it will do.

You can use the following code in the Python Console, script or plugin which sets the featureCount setting to be enabled for any loaded vector layer:

def showFeatureCount(layers):
    layer = layers[0]
    if layer.type() == QgsMapLayer.VectorLayer:
        root = QgsProject.instance().layerTreeRoot()
        myLayerNode = root.findLayer(layer.id())
        myLayerNode.setCustomProperty("showFeatureCount", True)

QgsProject.instance().legendLayersAdded.connect(showFeatureCount)

If you want this to work from startup, you can use a startup script (or a plugin) and use the code shown above in addition to importing the following modules:

from qgis.core import QgsMapLayer, QgsProject
