App Listing Quality on Flathub

[ryonakano]

Listing failed checks of the app:

• App Icon
  • [ ] Not too much or too little detail
  • [ ] No baked-in shadows
  • [ ] In line with contemporary styles
• App Name
  • [x] No weird formatting, punctuation, lowercase, etc.→Maybe complaining the trailing !. Should we remove it from the app name……? :thinking:
• Summary
  • [x] Shorter than 35 characters→I'll check now. (assignee: @ryonakano)→Fixed in #124
• Screenshots
  • [x] Reasonable window size→I'll take care on the next release. (assignee: @ryonakano)
  • [x] Good content→I'll take care on the next release. (assignee: @ryonakano)

I'm not sure if this blocks publishing future releases, but tagging as "Help Wanted" since I'm not good at designing icons :innocent:
