Great article. As you are likely not native English, just as a tip you can actually simplify a lot of statements by removing the word ‘the’. As one example:
> When the users need the features from Jira and request them to configure the plugins for many application scenarios, which contribute to the overall complexity of UIs.
Becomes
> When users need features from Jira they request plugins, which contributes to UI complexity.
> When the users need the features from Jira and request them to configure the plugins for many application scenarios, which contribute to the overall complexity of UIs.
Becomes
> When users need features from Jira they request plugins, which contributes to UI complexity.
Not a criticism - just thought this might help!
