Feature request: reopen files on launch

I'm really enjoying using MacVim – however one feature that I really miss from Sublime Text is the ability for the editor to automatically reopen whatever files were open when it last exited. Do you know if there are any plans to add this behavior to MacVim?

I'm guessing the simplest way to achieve this would be to store the arglist of each active vim process (i.e. one arglist per GUI window) on quit, and then on startup you could automatically spawn a new GUI window for each of these stored arglists – but then again I'm quite new to Vim and I don't know anything about the internals of MacVim so this could be a terrible approach :)

N.B. I'm not talking about restoring the full session state (tabs/splits/etc), seeing as that can easily be accomplished with autocommand-triggered user scripts via :mksession and :source. The missing piece of the puzzle seems to be automatically spawning the vim instances with the correct arglist in the first place…

首先跟踪 MacVim 的启动和退出行为，然后检查如何保存和恢复每个 GUI 窗口的 arglist。将所请求的行为与 issue 中现有的使用 :mksession 和 :source 的 workaround 进行比较。当之前打开的文件能够在相应的 GUI 窗口中重新打开，且不需要完整恢复 session 时，即视为完成。
