I'M BACK with my plea to PLEASE bring back the vowel markings native to MacOS keyboard

It's been a few months since my last plea, and with L9 coming out, it did not surprise me that my request was met with crickets from Logos/Faithlife...

But now that I bit and bought the system upgrade for L9, I installed it hoping that I would be able to press and hold a vowel on my Mac keyboard and have that vowel marking option window populate overhead.

But alas...when I typed, I typed didooooooooooomi  instead of didōmi (see, I can use it in this window, but not the app itself!)

And that workaround that was suggested to me several postings before—that I use the keyboard viewer and find the marking there? That gives me didõmi instead of didōmi.

And to make it more frustrating...that workaround was totally useless when I wanted to simply type agapē. I would find myself typing agap˜e, which looks totally ridiculous. So I would go for a (perhaps) less ridiculous option: agapë. But that is a different sound still than agapē. Or, I would press and hold the "e" and get agapeeeeeeeeee. 

So at the risk of being redundant, allow me to review my numerous posts to this forum in the past:

Back in the day of Logos 7 for Mac, I was able to utilize the vowel marking feature native to the Mac keyboard (i.e., I was able to press and hold the vowel key until the vowel marking options populated in a window above the vowel, then I was able to select the mark I wanted and we were good to go). But starting a couple of updates into Logos 8, that capability went away. I have had to substitute markings that were similar but not accurate (for instance, I have to use echõ instead of echō, and agapë instead of agapē). But since I copy some of these notes into Evernote, I am able to correct those markings in Evernote, since that app utilizes the Mac keyboard capabilities. 

So, will this plea to Logos to please include this feature get met with crickets yet again?
