Smart Bookmarks for YouTube: Productivity Up Chrome 插件, crx 扩展下载

扩展ID: ichpfnleoiponjidhcbieonjdpnallmh

Adds the ability to add a bookmark to any place on a YouTube video (aka time-tags, notes, private comments).This extension was written due to lack of a bookmarking system on YouTube and inspired by Pluralsight. I love the ability of Pluralsight to add to any place on a video my own thoughts, ideas and notes that have to be reviewed later or even exported and reviewed later on any other device in Evernote. So I've made something similar in a "Chrome Extension" form-factor!

You can add multi-line comments to any place on a video and they will be visible only to you (until you want to share them!). The focus of this extension is shifted towards usability. Hotkeys are supported — they work inside the pop-up window and directly on YouTube's page.

Depending on the interest in the extension a lot of features may be added later. Also, feedback is highly appreciated. So don't hesitate and support development!

You will be able to:
1. Add a bookmark to any video.
2. Control any video with hotkeys (play\pause\rewind).
3. Quickly navigate to any bookmark without reloading a video.
4. Manage any previously added bookmarks (edit/delete).
5. See a list of all videos with bookmarks (and manage it).
6. Export bookmarks to a clipboard (for sharing with others).
7. Import bookmarks from a clipboard (from a friend or just from 'backup').

Use cases (ideas):
1. Education and learning: Invest in yourself by learning from YouTube videos.
2. Entertainment: You can bookmark the funniest moments in any video and share them with your friend.
3. Cooking: Mark different stages of a cooking video in order to quickly find the most important parts for you. Then export the recipe!
4. Programming: Save places that contains code or something that requires additional attention or reviewing.
5. Create a table of contents (TOC) for a video—and share it with others via a comment on the video's page. Save time for someone and someone will save it for you.

Please support the extension development and help it grow!

## How does it work?
### Adding a bookmark
Just navigate to any YouTube video and click on the extension icon. The pop-up will be opened. In order to add a bookmark just press the '+' (add) button. The bookmark will be added immediately to the video but without text. In order to add a text description for the bookmark, click the 'edit' button. You'll be redirected to an editor. Add any text; press 'save'. Done!


### Navigating to a bookmark
In order to navigate to a bookmark (to go to a saved point in a video) just click on a bookmark. Try it.

### Exporting bookmarks for a video
The bookmarks can be exported only to a particular video (not all bookmarks for all videos). In order to export it, navigate to a video on YouTube, open the extension and then click on the 'More' button (three dots in the right top corner) and then 'Export'. It will export your bookmarks in a YAML format.

Another way is to export them in a 'simple' format—use the 'Export (simple)' button.

### Importing bookmarks for a video
! Important: when you import your bookmarks, the old ones will be removed. In order to import a previously exported bookmark, navigate to a video to which you want to import bookmarks, open the extension and then click on the 'More' button (three dots in the right top corner) and then click 'Import'. Paste the exported bookmarks into the opened window and press 'Import'.

## Hotkeys (works inside a pop-up)
The extension also supports hotkeys. They are:

Video navigation:
`Space` - play/pause
`Comma` - backward 5 seconds
`Period` - forward 5 seconds

Bookmarking:
`a` - add immediate bookmark
`shift+i` - add bookmark with a text
`i` - add text for an immediate bookmark

Editing a bookmark's text:
`enter` - save changes
`shift+enter` - add a new line
`ctrl+b` - cancel editing
