2.0.31 optimized many functions and experiences, and fixed many bugs. The brand new GUGA 2.0, the brand new GUGA function and experience, brings a total of more than 700 new functions and upgrades in six sectors. The six upgrade sections are "File Management System", "Notebook", "Whiteboard", "Card and Flash Card", "Inspiration Catcher" and "SharePlace Community" 1. Upgrade "File management system": Add "File Management" sidebar on the left, add "My Logbook" sidebar on the right; support multi-layer folders and multi-layer card packages; optimize the file management interface and operation; make your GUGA management more convenient. 2. Add "Notebook" function: From now on, you can import/create/use the notebook in the folder or in the whiteboard. GUGA supports multiple formats to import into notebooks, providing 100+ inner pages and cover templates; supports editing structured outlines, adding/deleting pages, and supporting notebook export. In addition, while handwriting, it supports long-pressing to select the content for annotation and excerpting; an unlimited number of handwritten layers can be added to each page of the notebook, and the layers can be hidden/displayed as you wish. 3. Upgrade "Whiteboard": Add "Notebook Floating Window Mode". Add "Frame management function". Support the export of all Frames (or select some Frames) as a PDF. The whiteboard supports "multi-level structure". Support the creation of a new subordinate "sub-whiteboard" in the whiteboard; a new whiteboard structure list, and a multi-layer whiteboard breadcrumb navigation bar. Optimize the "search" function, and the notebook/frame and cards in the current whiteboard will automatically appear in the search menu to help you find them more quickly. Finally, when importing a notebook/other whiteboard into a whiteboard, you can choose three ways, a. Copy; b. Move; c. Link mode. ( Among them, the Link mode means that the position of the original notebook/whiteboard remains unchanged, but only creates a linkage shortcut on the current whiteboard.) 4. Upgrade "card and flash card" function: We have optimized the card list interface and added the "multi-layer card package" function, which is convenient for you to better manage and use your favorite cards. For the block in the card, the "flash card answer status" function has been added. Whether the card is in the whiteboard or in the card package, you can easily switch any block between the answer status and ordinary status, so that you can better make the "flash card". Secondly, the "flash card package" function has been added, and any card package can be converted into a flash card package. Each flash card pack is a built-in memory algorithm (three kinds), automatically helps you arrange your learning plan, and a super learning tool with other related functions, which will help you learn and review the cards you make to the maximum extent. 5. Upgrade “Inspiration Catcher”: From now on, in the WeChat, you can freely choose the location where you want to store the subsequent inspiration shorthand cards (you need to create a new card package in GUGA first). 6. New "SharePlace Community": From now on, you can share your notebooks, learning materials and flash card packs to SharePlace, and you can also download content shared by other users from SharePlace.

The brand new GUGA 2.0, the brand new GUGA function and experience, brings a total of more than 700 new functions and upgrades in six sectors. The six upgrade sections are "File Management System", "Notebook", "Whiteboard", "Card and Flash Card", "Inspiration Catcher" and "SharePlace Community" 1. Upgrade "File management system": Add "File Management" sidebar on the left, add "My Logbook" sidebar on the right; support multi-layer folders and multi-layer card packages; optimize the file management interface and operation; make your GUGA management more convenient. 2. Add "Notebook" function: From now on, you can import/create/use the notebook in the folder or in the whiteboard. GUGA supports multiple formats to import into notebooks, providing 100+ inner pages and cover templates; supports editing structured outlines, adding/deleting pages, and supporting notebook export. In addition, while handwriting, it supports long-pressing to select the content for annotation and excerpting; an unlimited number of handwritten layers can be added to each page of the notebook, and the layers can be hidden/displayed as you wish. 3. Upgrade "Whiteboard": Add "Notebook Floating Window Mode". Add "Frame management function". Support the export of all Frames (or select some Frames) as a PDF.

Secondly, the "flash card package" function has been added, and any card package can be converted into a flash card package. Each flash card pack is a built-in memory algorithm (three kinds), automatically helps you arrange your learning plan, and a super learning tool with other related functions, which will help you learn and review the cards you make to the maximum extent. 5. Upgrade “Inspiration Catcher”: From now on, in the WeChat, you can freely choose the location where you want to store the subsequent inspiration shorthand cards (you need to create a new card package in GUGA first). 6.
