@ianclawson This is absolutely perfect, would it be difficult to throw in a commit to round the corners (like iOS does to it's icons) to show what the user exactly what the icon will look like?

And maybe "Pride 1" and "Pride 2" could be "Pride" and "Pride (Gradient)" - or do ya think the numbering looks better?

Appreciate the feedback! I much prefer your suggested "Pride" and "Pride (Gradient)" so I'll update accordingly 👍

For the rounded corners, I'll give it a shot! It's def possible using a custom cell (right now I'm using a default one) but I'll first try an approach using the default cell to see if I can make any gains there without extending the PR much more.

@lonkle updated! Adding the App Icon curve is such a nice touch -- I'm mad I didn't think of it! 😂 Thanks for the recommendation.

It looks great! And this is why we work on things together! Two pairs of eyes. 😉 I updated the Trello card cover image with your new screenshot and it looks awesome!

Closing this PR (kinda) in favor of another PR I will be opening in the next few days.

I just realized I'm working on 3 separate smaller QoL enhancements that all have to do with configuring the app's appearance in some way, and so realized from a UI perspective it makes sense to consolidate those into an "Appearance Settings" screen, therefore it would be cleaner to wrap all of those into a single PR.

I'm halfway through the final enhancement now, so I'm hoping to have the other PR ready by the end of the week 🤞
