How do you want to open the drawer? Upwards? You can chabge it to right/left swipe

If you mean the widget edit button, there’s plans to change it, and to add it to the three dots menu, afaik. In the meantime you can hide it in the settings.

How do you create webapps?

I click on install in fennec and it appears on my favorites list and I can search it, and tag it. It does not appear on the homescreen like on other launchers.

I don’t use work profiles anymore, I didn’t know that. Hopefully there’s already an issue for it on their github page
