Ideas for further tasks improvement

• better visual distinction between "done" and "not done" translations in task view (the icon on the right is not visible enough)
• right icon, should be reworked to not combine state indication and state transitions together (change to text, remove colors)
• "review & done" button - for review tasks (mark as reviewed icon is not visible enough and not clear)
• add filter for states
• put progress next to task label, so it's more clear what state it is in
• if buttons for state transitions are not clear, add icons

There is also serious issue that when task is finished and I remove a key the scope is changes and even the report is generated without the key. Modifying project scope should definitely not modify the finalized task scopes and reports.
