My Suggestion and Request on PxerStudio by BennyKok
Open Source Pixel Drawing Tool | Open source on GitHub

Components
The current features of the software are the following:
- Zoom and move but two fingers
- Support layers
- Support grid
- Unlimited undo, redo
- Color picker with alpha channel
- With fill, rect, pen, eyedropper tool
- Create canvas size up to 128 x 128
It is currently exportable to:
- Export to GIF
- PNG
- Sprite Atlas
Proposal
I would like to suggest the following:
-An addition of file formats like JPEG/JFIF, JPEG 2000, Exif, TIFF,
BMP, PPM, PGM, PBM, and PNM, WebP, HDR raster formats,
HEIF, BAT, BPG as many as possible.
-A user manual on how it will be use like links of sample videos or notes.
- An unlimited undo and redo button
- Improve/change the icons of each tools for example is the eraser.
It should look like an eraser. Be it more colorful and artistic.
Another concern is that the app crashes everytime when Menu icon (upper left) is clicked.
Mockups / Examples
These are the edited photos of my suggestions.

Benefits
Here are the benefits once my proposal for the components/parts/sections of the software will be implemented and solved:
-The users will not feel limited about exporting image into different file formats.
-The users will be able to understand the software faster than self-exploratory.
Especially to those who have an immediate project to be done.
- Unlimited undo and redo button for the users to recover and renew
all the processes they made.
- The users can do both. To create an artwork while enjoying it and loving it.
For the crash menu icon, so that the users will not hesitate to download the app based on the reviews also.Will not tend to uninstall it.
