Keyboard shortcuts issue and navigation glitches

There are a number of issues when it comes to keyboard navigation (in Windows).

One thing I've noticed visually, the selection is blinking when navigating through tasks and Goals/Projects (see video).

Sometimes, navigation with arrow keys isn't possible at all because suddenly they navigate the scrollbar and the only way to switch to the task selection that I've found, is to click on a task... clicking is not keyboard navigation.

This continues with editing tasks.

When one task is selected, how can I edit it? Enter/Return or classic Shift+F10 don't work. Ironically, in the contextual menu when right clicking a task, there are letters for keyboard navigation...

Other keyboard navigation won't work at all.

I wasn't able to get any of the G+ Go to... shotcuts working at all.

Neither have I been found a way to switch focus from the sidebar to the main panel.

Not being able to change keyboard shortcuts is a mayor flaw as well.

"Show/Hide Navigation" is Ctrl+/ ... and on a qwertz keyboard? Please think about the different keyboard layouts out there.

All in all, keyboard navigation feels very broken and very incomplete at the moment, at least on Windows.
