Hah: when I saw the screenshots, I thought the goal was to replace the WinUI 3 grid with a LIstView, which made me very conflicted.

In terms of testing this, please revisit all the resolved bugs on the program: there are lots of little things reported by people that wanted the app to be a "creator" rather than an "editor" which uncovered to issues with odd things. Like trailing comments on data lines or data that crosses over two lines but with added white space. Made the "parsing" routine a tad larger and convoluted, sort of like using bubble gum to plug holes.

I also assume that multiple languages were included in the testing, in addition to the emoji? When asked "why aren't you showing text for SZ_MULTI" I replied with NYI and ran away from the question! :)

Would it make sense to support Reg_Multi_Sz multi-line preview in a read-only content Dialog?

Hi @randyrants , do you feel the recent changes addressed your feedback? 😉

[randyrants]

LG2M! We'll know more as people start to run their files through it - that's where I found the majority of bugs with stuff like this.

@htcfreek What about showing it in a flyout or tooltip?

@dillydylann
Sounds good. I would prefer zhe flyout. Maybe we could add a glass in the datagrid that opens the flyout.

(Should I open a new issues?)
