@kittcatalina fist, my apologies for this late reply! Loading plugins in a custom order than they currently are is something that was barely requested for Asset CleanUp, thus other features had more priority when it comes to development. In an ideal scenario, if developers would follow WordPress standards, it shouldn’t matter in which order those plugins are triggered.
For instance, WooCommerce has lots of extensions and those extensions (especially the professional ones) are written in such a way that it shouldn’t even matter if the extension is loaded before the actual WooCommerce main plugin or if there are other 10 extensions installed there (no matter in which order they are triggering). For a newbie developer that is not yet fully familiar with the way WordPress works, he might be tempted to write a base plugin and an extension that should be loaded in a certain order. For instance, if the extension happens to be loaded before the main plugin, a PHP error would be triggered and the website won’t load anymore. The code has to be written in such a way that if an extension is triggered before the base plugin, no errors will be shown and the website will load as normal. Moreover, if the base plugin has been deactivated, then even if the extension plugin is active, it will be like it’s inactive since it has no usage without the base plugin extension.
Anyway, back to performance. Since the plugins are loaded in the backend and the HTML code resulting from those plugins is generated, what sometimes happens is that certain hardcoded STYLE/SCRIPT tags or enqueued CSS/JS that have the same priority when add_action() is used, are shown before/after another, but in terms of performance, this is actually not making any difference or at least it shouldn’t if the plugin is a professional one. There are rare cases (I don’t even recall when I had to change the order if the loaded assets, that’s how long it was) when you might need to alter the order of the plugins. Asset CleanUp doesn’t deal with that at least at this time, due to the very low demand.
If you check out the description of this plugin: https://ww.wp.xz.cn/plugins/plugins-load-order/ – you will notice the same thing I just explained above is also mentioned by the plugin’s developer:
If you are plugin developer, I encourage you to use actions and hooks so that you will not need this plugin at all, but if you are managing your own blog and you face to the problem a plugin depends on other one, then this is the plugin you need.
So, I strongly recommend the usage of actions & filters (the right way) whenever a plugin is developed and it depends on a base plugin.
