Enhance Taskview UX

When in task view if you want to add something (like substasks, internal and external links, attachments) you have to scan the left action list links, find your action and click on it. The actions list on the left is complete but is not handy. It should enhance a lot user experience if you can have a button in the “accordion” shown below the task resume. You can already follow this user pattern for comments. You open the task, expand the Comments accordion, write the text and click on Save.
Whe you open the project overview you can alread add attachments with this user pattern. Is it possible to have the same user pattern for tasks components group?
