Basically there are no problems with any of these. The only one causing crashing is the Song edit Title field.
Interestingly, it is possible to go into one of the textboxes as you describe below, type some text and then return to the Song edit Title and it will work ok (sometimes) without crashing. I have done this a few times with different textboxes but not sure if all cause this. Sometimes it does not work but if you go to another textbox then back to title, it will be ok and not crash.
In order to do these tests then, I had to swipe MS off the task manager then tap on it again to open it again, then test it would crash ok first, then test the next textbox. I also revisited the title crash from time to time to make sure it was still crashing (!)
I could do more thorough testing with a few more scenarios, it could become complicated. Let me know.

I will comment on each below.

- The search textboxes at the top of the main library screen. Typing in values should cause the list to be filtered based on name or, if using the custom box, the custom field

I went into Filter and played around with all the textboxes there, no crashes. Is this where you meant?

- While creating a new folder in the file browser, there is a field to enter a name.

I went to song edit and tapped the folder icon, then, from (the OS) options, was able to enter a folder name and create one ok into my SC card. Is this where you mean?

- While creating a library backup, a name must be entered.

No problems here.

- While creating a setlist or collection, a name must be entered for it. Also, if an existing setlist or collection is selected, they can be renamed by typing in the Active Setlist/Collection textbox at the top left

no problems naming or renaming a setlist nor collection.

- The convert PDF to image dialog has a few textboxes for entering numeric values

Where is this again?

- Options->About->Email zubersoft support provides a dialog where a message can be entered

I sent you a message, no crashing typing text.

- If a song is loaded, notes can be entered by tapping on the notes button at the top left. Long pressing and selecting "Edit Notes" can also be done on the library screen.

I was able to add text to the Notes window on a few songs.

- If a password protected PDF is loaded, a password must be entered

I have not tested this. Let me know if you want me to do this, I will have to create one.

- The sync screen shows a status log at the bottom that can actually be clicked on (which may trigger suggestions).

Yes found this, no crash. Suggestions box came up.
