Quickie for anyone around: how do I increase the font size of the items in the menu bar?

Menu bar for what OS?

@J.M. if it's the main menu bar that's specified at OS level I bet

How can I trace the internal methods that takes a Dataset and gives the formatted table interface?

Or really the methods that formats any expression for the frontend

Ok, I found Dataset`MakeDatasetBoxes but how am I supposed to find that in general

Look deeply at FormatValues[Dataset]?

(which is barely even documented)

@hftf the standard thing is to use GeneralUtilities`PrintDefinitionsLocal

I did some of that and found this: TypeSystem`NestedGrid`PackagePrivate`iDynamicNestedGrid

That's the core implementation you want

So use the same function on that

@b3m2a1 OS level, huh? Lemme check... (this would be both for Windows and Linux)

I use Mac and the main menu bar is common to all Mac processes so such a system would, I think, have to be unique to Windows / Linux, if there's customization possible from within the app.

Ah, found it for Windows, it's under Control Panel > Display. I'll try things on my Xubuntu box later. Thanks for the tip!

Is there a way to turn a package saved as mx format back into source code? I'm trying to debug internal TypeSystem functions using Workbench, and it's really difficult to not see the code, even though I know it's there with PrintDefinitionsLocal. The mx file in question is SystemFiles/Components/TypeSystem/Kernel/64Bit/TypeSystem.mx

Looking at tutorial/FilesForPackages

OK reading mathematica.stackexchange.com/questions/1742/…

OK, I didn't realize FullDefinition is a thing
