Implement 'Open Recent' feature (open to user-submitted PR?)

[andrewdbond]

I have a lot of issues to go through, so in order to make it easier for me to help you, I ask that you please try these things first

• Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• See if someone already suggested this under Issues or Discussions

Description

1. Many apps (such as Microsoft Office, etc.) have an "Open Recent" or similar
   menu item under the File menu. In LosslessCut, this could list recent source
   videos (and optionally project files, exported videos, etc.).
   @mifi are you open to this functionality, either as a user-submitted PR or
   implemented yourself (as I don't know your preferences)?

2. If you're open to part 1, optional extra semi-related functionality:

   1. LosslessCut could automatically restore cut times for recent files. I'd
      love to see it remembered for many recent files (20? 100?), but even if only
      remembered for the most recent file that would be better than nothing for me.
      LosslessCut would store the times in its existing common settings file or
      similar. This functionality has overlap with project files but would be
      automatic without creating extra user filesystem files.

   2. If LosslessCut remembered recent files and/or exports, loading an
      exported video could prompt the user if they want to instead load the
      original source video using the previous cut times. LosslessCut could
      remember recent cut times in its settings file, or autoload cut times if the
      user used the standard export filename format.

   For part 2, LosslessCut could match videos based on full path, or if no full
   path matches, filename match.
   Are you open to any/all of these ideas?

Hi!

• Many apps (such as Microsoft Office, etc.) have an "Open Recent" or similar
  menu item under the File menu. In LosslessCut, this could list recent source

This sounds like a good feature to have. However I think before implementing too many new features that cross the main-renderer-process-boundary in electron I think I want to #1377 - or else that job is going to grow bigger in the future. E.g. I don't want to add any more features depending on @electron/remote or nodeIntegration right now.

• LosslessCut could automatically restore cut times for recent files. I'd
  love to see it remembered for many recent files (20? 100?), but even if only
  remembered for the most recent file that would be better than nothing for me.
  LosslessCut would store the times in its existing common settings file or
  similar. This functionality has overlap with project files but would be
  automatic without creating extra user filesystem files.

So you mean have an option to disable project files (already exists), and another option to save/load cutpoints per file in one central location (e.g. user's app data folder)?

2. If LosslessCut remembered recent files and/or exports, loading an
exported video could prompt the user if they want to instead load the
original source video using the previous cut times. LosslessCut could
remember recent cut times in its settings file, or autoload cut times if the
user used the standard export filename format.

Not sure what is the use case for this. I've never heard it requested before but can leave it open to see if more interest. Is it related to #1385 ?
