You sit down to use Decker, the retro-computing love letter to HyperCard. You’re excited. You start typing. Then you notice: there’s no way to change the font size. No slider. No dropdown. Just a heading toggle. You’re annoyed. You’re frustrated. You’re about to close the tab.
But that frustration? That’s exactly the point.
Decker isn’t broken. It’s making a philosophical statement about who this tool is for. The missing font size control isn’t an oversight—it’s a filter. A very intentional one.
Let me tell you what happened when I tried to use Decker last week. I wanted to make a simple card—a title, a body, a little personality. I reached for the font size options. Nothing. I checked the docs. Nothing. I went to the forums. And there it was: another user asking the same question, getting silence. That’s when the twist hit me. The silence was the answer.
We’ve been trained to expect granular control. Every modern tool gives us a thousand knobs. We’re conditioned to believe that more options equal better tools. But Decker takes the opposite bet: constraints aren’t bugs—they’re design decisions that shape the entire experience.
Think about it. If you can’t adjust font size, you stop thinking about typography. You start thinking about what you’re actually saying. The absence of a feature forces you to engage with the core purpose of the tool: creating and sharing ideas on a simple card. Not designing a magazine layout. Not finessing kerning. Just writing.
This is where the Mimeng principle of emotion first comes in. The frustration you feel is the hook. But the payoff is a deeper understanding: the best tools don’t give you everything you want—they give you exactly what you need to do the thing that matters.
And who is Decker for? People who remember the joy of HyperCard. People who miss the days when software had a soul, not a million settings. People who are willing to trade a little comfort for a lot of focus. The missing font size is a test: if you can’t handle it, Decker isn’t for you. That’s not arrogance—it’s clarity.
I’ve seen this pattern before. The original Super Nintendo had a fixed resolution. The iPhone’s first camera had no flash. Basecamp famously limits features to keep products simple. Every constraint is a decision about who you serve and who you’re willing to lose.
So the next time you’re building a product, ask yourself: what are you willing to leave out? Not because you can’t build it, but because leaving it out makes the experience stronger. Decker’s missing font size isn’t a bug. It’s a manifesto.
FAQ
Q: Isn't lack of font size adjustment a serious usability flaw?
A: Only if you define usability as 'maximum flexibility.' Decker prioritizes constraint over choice. For users who need accessibility, yes, it's a problem. But the tool's philosophy is about intentional limitation—you're not the target audience if you require that control.
Q: What practical lesson can product designers take from this?
A: Every feature you add is a decision about who you exclude by inclusion. Decker teaches us that the most powerful design move is often what you leave out. Ask: 'What experience am I protecting by not adding this?'
Q: Isn't this just gatekeeping? Why should anyone celebrate missing features?
A: Respecting the user means being honest about who the tool is for. Decker doesn't pretend to be a general-purpose platform. That honesty is rare. It's not gatekeeping—it's identity. And identity is the only thing that survives in a sea of me-too software.
