Making steps towards stable E2EE, we have now implemented bootstrapping cross-signing on a new account. This allowed me to finally enable cross-signing on my Nico (nheko.im) account (which I intended to only use with Nheko). Thulinma also added a way to refresh the current device list as well as highlighting your current device in the device list, which should make it easier to recover, if a misscommunitcation with the server lead to an outdated device list. Meanwhile LorenDB has been plugging away on converting more dialogs to Qml and we merged like 3 converted dialogs!
