If this is any good I'll be considering it as a replacemnt for Keepass.
A bit off topic, but while looking at this I noticed another expirement - Firefox Side View. It looks like it lets you have two open tabs side-by-side in one browser window. This is exactly why I used the Tile Tabs[0] extension and had to switch to Tile Tabs WE[1] with the Quantum update. I'm happy to see this coming back without the WE workarounds.
