When application names get too long in Application Dashboard, they get elided. There is no way to see their full name, which is problematic especially if two names only differ near their end. Full application names should be shown on hover, either in a tooltip or by temporarily expanding the name of the application currently hovered over. Reproducible: Always
Unfortunately it doesn't seem possible (not without making showTooltip publicly accessible from QML which I'm not sure we want) to use a single ToolTip item for multiple cells, like it does with the MouseArea.
The same thing happens for filenames that show up with Desktop search. If you have a string that matches 2 similar filenames, there's no way of telling which one is the one you want because only the first several letters show up. May I suggest that there be an option to show results as a horizontal list also? That'll take care of the attenuation without needing tooltips.

There are tooltips now.
