+# vim-workspace
+
+Automated Vim session management with file auto-save and persistent undo history 
+
+The configuration of the plugin:
+
+- disable resession.nvim - default astronvim session management
+- auto create and auto load the workspace when neovim was started without any arguments
+   - just `cd dir` and `nvim` to start the workspace
+- auto save the workspace when neovim was closed
+- handle neotree, NERDTree, git windows
+- fix paths to use cache path of neovim
