Feature request: parameters input

Let's try to draw a rectangle.
Enable orthogonal restriction.
Click somewhere to start a 2-point line.
It would be very convenient to be able to just move a mouse in a direction of a line (horizontal or vertical) and then just enter a length of a line. Just like it is made in AutoCAD. And yes, I understand that it can be done by entering "@100<90", but it's much easier to enter just "100".

And actually it can be said about all the other tools - to be able just to enter the number for needed parameter after clicking the button or invoking the command in command line. Just like it is made in "Circle -> Center,Point" command - so you click where you want a center to be and then just enter the number for a radius, great. So why in the "Circle -> Center,Radius" it is not the same? Doesn't make much sense to me.

I can't express how important this feature is.  In engineering I don't give a darn about coordinates.  I want to specify an origin point and dimensions of an object (like a rectangle).   I shouldn't have to sit at the keyboard with a calculator trying to figure out the size and how much I need to add/subtract to get the object to it's correct size.

Welcome ForestEP1!

This feature request is about more simplification of the existing routine to enter relative coordinates. This might be more confusing for new users.

What you are looking for are relaive coordinates, to create entities by dimension.
See https://docs.librecad.org/en/latest/ref/fundamentals.html#relative

well, this feature will be available soon in 2.2.2-alpha as I'll make a pull request.

Something like next week or so.

I hope my changes will be merged into master branch soon and thus this functionality will be available in 2.2.2-alpha (development version).

As far as I understand, you refer to something like this:
