Adobe Acrobat Reader Tabs Saving And Autoloading
Thanks for the fantastic start to implementing this glaring feature omission from a mature product. An Autohotkey script will accomplish what you're looking for. I've created one below that will automatically save the tab layout when you close Acrobat.
This script works with the latest version of Acrobat Pro DC. In this version, the script menu options appear at the bottom of the "view" menu. If your version differs, you'll have to modify this script; please report in the comments if your Acrobat version puts the custom Javascript menu options elsewhere.
if WinActive("ahk_class #32770") & WinActive("Adobe Acrobat", "Do you want to close all tabs or the current tab") { Send, !c WinWaitActive, ahk_class AcrobatSDIWindow Send, !v{Up 3}{Enter} WinWaitActive, Warning: JavaScript, Tabs Saved Send, {Space} WinMenuSelectItem, ahk_class AcrobatSDIWindow, , View, Save Tabs Send, ^q}
