Having multiple tabs with different files at the same time can be helpful. Can we add a tab feature.

Don't look at me for this one: I hate tabs. I hated MDI windows years ago. Rejoiced for years, when Office sent each document to its own window instead of having a single app window with multiple files in it.

It's as big (or spiritual) a thing for me, on par with the people that argue tabs versus spaces in source code.

Whitespace around other parts of the line, not just the beginning of the line, also causes issues.

regedit accepts whitespace around these tokens, so Registry Preview should, too. 🙂

You misunderstood something here. What I mean with this issue is having ui tabs for multiple files. 😅

@qJake, tabs and this are different.

@Jay-o-Way i don't think this this is a large scope item

My bad! I searched for a whitespace issue before posting mine, and this came up. Thanks for clarifying the title! 👍
