Is there any way I can have a kind of "split-view" where I can look at the disassembly of two different portions of the code(of a single file) in IDA? It'd be nice to be able to do that.
You can open multiple disassembly MDI windows by going to
View → Open subviews → Disassembly in IDA's menubar. For example, if you already have a disassembly window open and open a new disassembly subview, your original disassembly window tab will be named
IDA View-A and your new disassembly window tab will be named
IDA View-B. You can then rearrange the disassembly windows (drag and drop the window tabs) to create a split-view.
