It would increase the revenues but would lose the sustainability.
So Inkdrop will be more sustainable if you get less money? That’s… …interesting.
In notes, people refer to things. Some of those things are in documents that it makes sense directly to attach. Attachments aren’t always images. That is why Google Calendar has attachments, that’s why Evernote and Bear also has them and not just for images. How well would those products have done if they had only attached images? Worse. Why? Because they would have been less useful.
Features that lead to more features.
For example, if the app supported PDF format, some people may want a built-in viewer and a full-text search support for pdf files, just like Evernote, even though you don’t need it.
You mean you don’t need it. In any case, allowing different formats for attachments in no way commits you to developing lots of other features. It’s the same thing you can do for images already, just for other formats. To make that more clear: when you decided to allow image attachments, you clearly didn’t worry that people would demand an image editor function, and various Photoshop like features. Because that’s not a risk. So the reason you give (“features that lead to more features”) doesn’t make sense.
It’s up to you, craftzdog, but Boostnote is hot on your trail, it already allows attachments of all formats and its free. You could listen to your customer base, as most successful products do, and have more of our money, or you can hold out until Boostnote has caught up and people just go with them. When that happens, tell us again about “sustainability”.
