@sindresorhus, what do you think about this way of fixing things (just throwing in if statements everywhere to check if user has the new design). Other solution would be making two function for each feature (one for new design and one for old and calling them separately. That might be cleaner but it worries me that there would be a lot of duplicate code. What is your opinion on this?

Seems ok.

@dusansimic Maybe we should merge this now, do a release, and then you can continue the rest of the items in a new PR? Just to get the fixes out there.

Agreed. I'm making this a regular pr and I'll start working on other issues in specific PR-s for each issue from now on.

[sindresorhus]

Can you make the titlebar draggable on the new design? I don't think we can ship it before that's done as the window cannot be moved.

[dusansimic]

Yeah, I don't have a Mac but there was already an issue open about this #1488. Does this seem fine or should we hide the profile picture and the Chats label. Since I don't have a Mac, maybe we should do the cosmetic fixes later?

[sindresorhus]

Seems fine. We can do the cosmetic fixes later.

[dusansimic]

I've added the CSS styles from the issue I've mentioned. Please check if it works.

[sindresorhus]

Nice work!

Show Unread Badge isn't fixed, it was for some time, but isn't working anymore.
