Some tweaks needed and bugs I noticed

[Deele]

• Button "System Activity List" should have link not "projects/activity" but just "activity"
• At reports overview page, the title should be H2, look at other pages it is standart, otherwise, it messes up theme style.
• Top menu should be shorter or without icons cause it is too long menu, for horizontal menu. I think, you hsould remove items, that are links to existing redmine functionallity and leave only links to tolls, you have created, e.g. All Issues, System Activity List, Spent Time Details, Spent Time Summary Reports, Calendar, Gantt should be without icons, or in another line, or removed compleatly, as unnessesary.
• At date selection at both report pages, there should be buttons with templates, like "Last 7 days", "Last 30 days", "This week", "This month", "This year", etc
• When user is selected and report generation is applied, there is no way to deselect user, and select role, for example.
• And last, feature request: there should be listbox to choose project or eaven select many projects, for which to create report
