Issues page sidebar - Link to issues page
You might be wondering why anyone wants to have a link to the issues page in the sidebar of the issues page, but the reason is as follows:
When you are in the issues view of a project, you can set a filter and - permission provided - switch between different views (Gantt, Calendar, Issues) without losing the filter settings by using the respective links in the projects menu:

In the "global" issues view, you only can only switch between the views using the links in the sidebar. There you have "filter-keeping" links to the Gantt view and to the Calendar view (again, permission provided). But what you do not have there is a link which brings you from the Gantt view or the Calendar view back to the issues view without losing the filter settings! Therefore I created this patch, to also have a "filter-keeping" link to the issues view in the sidebar:
