Ability to change fonts displayed in the app, their size, and the colours used.
Ability to delete an action step on the cards (If this is already possible, I couldn’t find a way to do it)
The option to add images (card background, action step icons and/or a picture directly related to each card/action step).
Perhaps a more in-depth users guide to aid new users in navigating through the app.
The ability to add hyperlinks in the cards.
Feasibility of allowing “idea lines” to be drawn connecting cards together visually. Perhaps even different colour lines representing different core subjects/ideas. A good name would be “IdeaLines,” which would stay true to the Idea theme you rock so well!
Perhaps this is a “pipe dream” request, but I believe a most brilliant idea would be for the app to have an optional keyboard exclusive to this app in order to boost the number of options available to be utilized whilst customizing the app.
These are my initial brainstorming ideas. I shall endeavor to submit more if it would be helpful.
