An easy way to keep track of the SharePoint document repositories is to bookmark the website links. Ensure that the bookmarks bar is enabled. Follow these instructions on how to enable it on Chrome. Here is a step by step guide on how to bookmark links:
- Go to the SharePoint site you want to bookmark
- Click on the star icon on the top right and click Add bookmark
- Choose the folder you want to save it in (I prefer to create a separate folder for just SharePoint) then click Done
If you would like to edit the bookmarks, simply drag it along the bookmark bar to where you want it to be. You can also create folder's by right-clicking the bar and selecting Add folder... Follow these instructions for more information about the bookmark bar in Chrome.
