why not more letters for the "sections" in editor?

It would be better if the user can "personalize" the sections name (A, B, C, D, IN, VS) with other letters, useful if you are writing a long song.

You can personalize (amend) the rehearsal marks using the text feature.

A1, A2, etc.

Both the IN (intro) and V (verse) marks are used to instruct the player to play that section just once. (unless instructed otherwise by a D.C. or D.S.)

The A rehearsal mark (and maybe others as well) indicates to the player that the intro or verse is done and the (repeating) form for the player begins here.

In the iOS app it appears that "emoji's" can be entered to indicate points in a chart with greater visual impact than text alone.
I haven't yet confirmed that doesn't create issues with the player.

For example:
1⃣ 2⃣ 3⃣ 4⃣ 5⃣ 6⃣ 7⃣ 8⃣ 9⃣

The added ”marks” are displayed differently on both my android device and older ”iReal b" iPad than on my newer iReal pro iPad mini (on which I created the example chart) but the marks are still visually distinctive.

Remember, there may be limited available space for additional keys in the iOS and android apps.
