Hello,
About me: I am a manager (aka administrator) in six companies and a 3D artist, I have a lot of tasks and deadlines that I needed to organize, so I was forced to look for a tool to organize my affairs.

I faced the problem that I cannot separate, hide, fully complete the tasks that I need to perform, since I have two different areas of activity that should not intersect, there are a lot of tasks, so for one workspace this is too much.
I will give an example:
I need to create a working 3D model for work in Unreal Engine, for this the model must have a shape, the shape must have its own features, it must also have a texture, there are also several of them, then animation, animation also has several types (idle animation, walking, running, etc.), visual effects, the skeleton of the model itself.
Only for one task here already used:

Boards - animation, mesh, etc
Sections - What is in progress, what is planned
Tasks - what model to animate, consider that I have more than one model
Checklist - what part to animate or what type of animation to make (idle animation, walking animation, running animation)

To mark what I am doing today, this is already a huge list that is difficult to divide, now imagine the work of a manager at a manufacturing company, whose product goes through all stages from the idea to sale on the shelves, as well as the lists of a 3D artist.

What I suggest - for the workspace add the title categories "Environment":

Workspace
↳ Environment #1 (3D art)
Board #1
Board #2
...
↳ Environment #2 (Management)
Board #1
Board #2
...

I also suggest a system for moving a product between Boards.
For example, a product has passed the idea stage and needs to be sent for implementation. Artists prepare a layout and offer developers to develop a product. The person responsible for the Board (Design) moves the Task (the product itself) to the Board (development)
A request is created to accept the task, and it appears in the main chat of the environment that it was ready and moved to a new section.
The head of the second Board (Development) considers whether everything is in order and accepts the Task to the Board or rejects it with a comment (if rejected, a comment is required), and also notifies the head of the first Board that the Task was rejected.

Also, when creating a comment, add the ability to mark exactly where the problem is and create a link to move to this section, as is done with adding tasks to the list.
For example, I need to mark that the animation of the legs is incorrect, I write:
"Incorrect animation of the right leg"
/Board/Task/Checklist#4 (it will create an automatic path to this place and create a link to the fourth item of the checklist, which has the name "Legs" (for example), and also mark the Task and a specific item in the Checklist with the ⚠️ icon, when clicked, a comment will appear.
The same can be implemented for the Board head, who, when unchecking the "done" mark, can return the checklist item from the crossed out state with the same sign and comment.
The person responsible for this task will be notified.
If you do not create a path to a specific checklist, then only the task itself will be marked.

And add the ability to hide other Environments while working with one of them. When choosing tasks for today, add the ability to choose in which environment the work will be performed. The implementation is not difficult if you think of environments as folders.

Also add the ability to clone the Task and inherit.
Cloning: the task will be completely copied, leaving it marked as done in one Board but will be reopened in the second Board, preserving everything items.
Inheritance: the same as moving, but the tags are copied (optional which ones), if they are in this Board too, as well as the ability to supplement the checklist with additional items.
Also add the ability to move Boards between Environments (this will definitely be useful for someone)

With such capabilities, integrating the application into manufacturing companies would be much easier.

I would like to write a few more words about other small details. The mobile version does not have a menu button on the main page, which does not provide quick access to the settings.
The dark theme is more like the Windows "high contrast" theme, which simply eats away at the eyes (I hope you understand what I mean)
