Let’s have new freshened modern look. . . The leather book look is getting very tired.
I agree. And also the capability to add png or jpg stickers to calendar pages to personalize reminders.
I disagree. The Filofax style look is what makes Opus One stand out from other apps. Maybe adding different skins to customise the look,to add to the apps originality, would be an option? Removing it will just make it look like any other app. If it ain’t broke don’t fix it comes to mind.
Why not provide the option?
I’m not sure why I would want to provide the option. I’m happy with how it is and I did also add that adding new skins (themes) would possibly be an option. I can’t see the point in changing things for changes sake. Now new features to add improvements to an app is a different matter.
Because your customer base wants it. Why not please your customer base?
5 people have ticked to agree with your suggestion. I’m sure the customer base is a lot bigger than that. At the end of the day we’re all part of the customer base, and each customer has their own opinions regarding aesthetic changes. This is just my opinion, and you’re as much entitled to yours.

With all the cusotmizations that can be done within different UIs, it would be amazing to see this happen - each customer could decide whether to keep the old-school binder format (which I do love) but could also enhance with a fresher look when desired.
