I'm going to build one and viewing a dollar or euro price would be nice :)

I wonder if that rp2.bootsel_button() function can be put to more than just one-time use.

Just throwing some ideas out:

Regarding how many functions that bootsel_button might represent:

• quick press is interpreted as "next"
• long press (0.5s to 2s) is interpreted as "previous"
• super-long press (5s) is interpreted as "leave application mode, go directly to config mode"
  ???

Regarding the "next" and "previous" functionality: maybe it's useful for switching through "modes"?

Perhaps not all modes are interesting, so they could be enabled via checkboxes/multiselect in settings so that user could avoid modes they never want to see?

Perhaps there is a setting for "auto-next-mode" in settings, which represents how long each "mode" should remain on the display. If set to 0 then mode is never changed except via the bootsel_button, else its value could be 30 if they want the mode to change every 30s?

As an example, assuming that a European user only had some modes enabled, "next" might increment as follows:

blockheight, sats per euro, sat-fees
blockheight, sats per euro, euro-fees
blockheight, europrice, sat-fees
blockheight, europrice, euro-fees
blockheight, sats zapped, sat-fees
blockheight, sats zapped, euro-fees
blockheight, euros zapped, sat-fees
blockheight, euros zapped, euro-fees
blocks to halving, sats per euro, sat-fees
blocks to halving, sats per euro, euro-fees
blocks to halving, europrice, sat-fees
blocks to halving, europrice, euro-fees
blocks to halving, sats zapped, sat-fees
blocks to halving, sats zapped, euro-fees
blocks to halving, euros zapped, sat-fees
blocks to halving, euros zapped, euro-fees
blockheight, sats per euro, sat-fees (...and we're back to the first mode)

... while v0.2.0-beta modes would increment as follows:

Block Time, Moscow Time (satsymbol icon), Transaction Fees
Block Time, Moscow Time (sat/USD icon), Transaction Fees
Block Time, Moscow Time (noicon), Transaction Fees
Block Time, Fiat Price ($), Transaction Fees
Block Time, Fiat Price (€), Transaction Fees
Halving Countdown, Moscow Time (satsymbol icon), Transaction Fees
Halving Countdown, Moscow Time (sat/USD icon), Transaction Fees
Halving Countdown, Moscow Time (noicon), Transaction Fees
Halving Countdown, Fiat Price ($), Transaction Fees
Halving Countdown, Fiat Price (€), Transaction Fees
Nostr Zap Counter, Moscow Time (satsymbol icon), Transaction Fees
Nostr Zap Counter, Moscow Time (sat/USD icon), Transaction Fees
Nostr Zap Counter, Moscow Time (noicon), Transaction Fees
Nostr Zap Counter, Fiat Price ($), Transaction Fees
Nostr Zap Counter, Fiat Price (€), Transaction Fees
Block Time, Moscow Time (satsymbol icon), Transaction Fees (...and we're back to the first mode)

???

I'm exploring ideas in a "brainstorm" branch here

...and I've implemented these ideas in a "clicky_dispversion_modes" branch here
however, while I have no waveshare screen at present, would have to remove edits that I made in displayBlockMoscowFees.py where I commented like "#NO_SCREEN_AVAILABLE#".
