Hi there (@Jeto)! 
This is my 1st post here so be gentle! 
Would it be possible to have a 1 hour ‘Tribute Timer’ that remains visible at all times (even in battle) tucked away (e.g. in the top right corner of the screen) please?
Another option could be to have a notification that pops up when your tribute is ready, and doesn’t leave until you touch your controller (e.g. TRIBUTE IS READY!).
In an ideal scenario, we could have both! 
I’m always late in noticing my tribute is ready (because I’m focused on a game mode), and don’t want to have to resort to setting a separate timer (e.g. on my phone).
Please let me know if you could mention this to the devs, and possibly release in the next patch/update.
Many thanks!
