right now we cannot have those edited inline, though sometime in the future, will look. However, you do not need to go to the dashboard to get to the portfolio editor. We give you multiple ways to get to it right on the portfolio window.
1) There is (by default) an "Edit Portfolios" button in the QAT (Quick Access Toolbar - shows on left side of the portfolio caption). Looks like a grid with a pencil pointing to it.
2) If you have the ribbon toolbar open, note that the stuff there is in groups. The first group is "Portfolio" where you have the Portfolio dropdown list as well as the quote source dropdown list. look on the bottom right of the group. Noe that there is a little box with an arrow there. Clicking on it will also bring up the portfolio editor
In both cases, the portfolio editor will come up with the current portfolio already selected.
As for the dashboard, if you do need to get to it, in most cases you can just use the Dropdown Dashboard. hit the F12 key on almost any MT window or the 4 color button on top right of the window. If you wish to bring up the main dashboard window (it lets you see more stuff, like sources, Open windows, etc) you can hit SHIFT+F12 on any window.
