Post actions on articles list are difficult to trigger on touch screen devices #309

Describe the bug

Accessing post modification buttons on an touch screen is difficult because they only appear on hover.

Steps to reproduce (if necessary)

Steps to reproduce the behavior:

1. Go to the articles list
2. Try to click on a button on a device with a touch screen and no mouse pointer
3. It's very hard, you need to think about where the button is going to be and try to tap it

Expected behavior

The buttons should always be visible (maybe dimmer) or in a menu that we can click on safely without triggering an action.

Application configuration
