I have verified that all the signs are still available in the Shop when using the desktop app.

I have verified that none of the signs are available in the Shop when using the Android app. I have no way to test the iOS app, but my best guess is that it behave similarly to the Android app.

I agree with the user above. Go to the TrainStation Forum and
 * 1) look for a thread about this subject. I can almost guarantee that someone else has asked this question already, or made a suggestion for this improvement already. If you find such a thread, add a comment to it. The more people who ask for this feature, the more likely the developers will add it, and the more likely they will do it quickly. If your searches do not find such a thread, then
 * 2) create a new thread. My advice would be to skip asking questions and to go directly to suggesting that the buildings and decorations be grouped by their themes in the mobile app, just as they already are in the desktop app. After making your suggestion, wait seven days for a response from Pixel. If there's no reply from a company representative after a week, then
 * 3) submit a Support ticket.
