I know that the platform can be used on mobile device but its not easy accessible - could you look into an app?
When you at-tag a user the cursor sits at the end of that user's name. As a result, you have to hit space to successfully at-tag that person. This experience feels a little off. When you at-tag someone, what if it auto-spaced so that you can continue typing more naturally. As an example, Slack works this way.
Suggest to have an app version of IdeaScale for iOS and Android users. A big chunk of our employees are non-office based hence they interact to ideaScale using their mobile devices.
Having an app should give a better user experience overall. (eliminates having to remember community URLs, key in password, occasional alignment / wrapping of text issue etc.)
