InfiniPaint, an infinite canvas with infinite zoom and online collaboration

I wanted to share a program I've been working on for a bit less than a year now. InfiniPaint is a collaborative, infinite canvas note-taking/drawing app. The biggest distinguishing feature of this application is that there is no zoom in or zoom out limit. Other than that, InfiniPaint's features include:

• Open online lobbies for collaboration
  • Text chat with others in the lobby
  • Jump to the location of other players through the player list
  • See other members draw in real time
  • Although this is a feature, you can also choose to completely forget about it. This app can be used offline
• Graphics tablet support (Pressure sensitive brush and eraser detection)
• Layers with blend modes and opacity. Layers can be sorted into folders with their own blend mode and opacity
• Save/load projects
• Saveable color palettes
• Quick menu usable by right clicking on the canvas, which can be used to:
  • Quickly change brush colors using the currently selected color palette
  • Rotate the canvas
• Place bookmarks on the canvas to jump to later. Bookmarks can be sorted into folders
• Undo/Redo
• PNG, JPG, WEBP export of specific parts of the canvas at any resolution (Screenshot)
• SVG export of specific parts of the canvas (Screenshot)
• Transform (Move, Scale, Rotate) any object on the canvas (Rectangle Select Tool/Lasso Select Tool)
• Display Images and animated GIFs on the canvas
  • Note: May take a lot of memory to store and display images compared to other objects, especially GIFs
• Hide (or unhide) the UI by pressing Tab
• Remappable keybinds
• Create custom UI themes
• Place infinite square grids on the canvas as guides for drawing
  • Grids come with various properties, including changing color, and displaying coordinate axes
• Textbox tool with formatting support (Bold, italics, underline, strikethrough, overline, fonts, text color, highlight color, text size, paragraph alignment, text direction)
• Other tools: Rectangle, Ellipse, Line, Eye dropper/color picker, Edit/cursor
• Can copy/paste selected objects (Ctrl-C Ctrl-V). This can also be done between different files, as long as they're open in different tabs in the same window
