Preface:
1. Some players said they hoped for a `lock` feature. After thinking for a while about how to implement it, I completed this lock feature;
2. After locking, the catgirl is still there, but moving and zooming are disabled;
3. At the same time, when the mouse moves over, the catgirl becomes transparent so players can see the desktop below;
4. Also, click-through is enabled, so even though the catgirl exists at this position, it won't block or interfere with the player's desktop operations;
New Features:
1. Lock feature: hovering the mouse over the catgirl now shows a lock button; after locking, the catgirl cannot be moved, and the mouse can click through the catgirl to the desktop;
2. Tray icon: right-clicking now reveals a `Control Panel` button that opens the control panel;
Optimizations:
1. Optimized the click-through clipping behavior of some interfaces;
2. Made the cat paw pop up more instantly when typing on the keyboard or using the mouse;
Multiplayer:
1. Optimized the multiplayer UI layout, and added the ability to switch to view the current room list while in a multiplayer room;
2. Improved the logic for inviting friends; fixed a bug where, in certain situations, friends could be invited repeatedly (which becomes a form of harassment);
3. Optimized and fixed network jitter issues: when network jitter caused a temporary loss of connection with Steam, players would leave a friend's room and never return;
4. Clicking the reset button on the tray icon to reset the main panel position now also moves multiplayer friends' positions in sync;
5. The multiplayer room name now defaults to the player's name first;
6. Optimized the layer sorting of prop decorations so that, in multiplayer, the catgirl's image is no longer covered by other players' props;
BUG:
1. Optimized and fixed based on feedback from specific players: after entering sleep mode (all screens off), when recovering, all catgirl panels, including those of multiplayer friends, would reset to their initial position;
