Optimizations

Plugin configuration 87% from 29 tests

readme.txt 88% from 16 tests

Often overlooked, readme.txt is one of the most important files in your plugin
Attributes that require attention:
  • Tags: Please reduce the number of tags, currently 12 tag instead of maximum 10
  • Screenshots: These screenshots do not have images: #1 (Manage all of your posts in Canvasflow from your WordPress dashboard), #2 (Easily select which posts are eligible for upload to your Canvasflow publication), #3 (Override the style an article inherits on a per upload basis.), #4 (Real time sync status manages and notifies you of all content changes), #5 (Customise the plugin to match your workflow.)
The official readme.txt is a good inspiration

canvasflow/canvasflow-plugin.php 85% from 13 tests

The entry point to "Canvasflow for WordPress" version 1.5.5 is a PHP file that has certain tags in its header comment area
It is important to fix the following:
  • Text Domain: You no longer need to specify the text domain since WordPress 4.6; it must be the same as the plugin slug
  • Main file name: Please rename the main PHP file in this plugin to the plugin slug ("canvasflow.php" instead of "canvasflow-plugin.php")
