New in Blender (coming from Modo) I am trying to give it a try to Blender. After the 2.8 update I got totally in (visually) at least. 

I am trying to explore the UI and I find a few differences that I am trying to understand. This is not a critic it is just doubts that I am trying to solve. 


In Modo when I move a vertex or any other element of the geometry the "coordinates" are 0 from the beginning. For ex. If I grab an upper vertex of a cube and I click the move tool any units input will be 0+ X . 
In blender the vertex of a cube has already the position in the space embedded, making my decitions little bit more complex. If I want to make a change in a vertex that vertex of the cube will not be 0, but 2m for example. Therefore If I want to move it 2mm ...I need to put 2002. 


Is it possible to use it as in Modo ? 


Is the boolean tool add-on working in 2.8 ?
Is there any shortcut to see my mesh subdivided view ? I mean in Modo when you press TAB it will swap to the subd version of that mesh. In Blender I need to open a modifier and activate it each time. I would like to have a short cut that that allows me to toggle the view of the subd vs regular mesh. 
I am still not getting use to move the geometry parts with the shortcuts...I am coming from the product design field and I feel more comfortable moving things with a gizmo. Any option to have it always active when I press G ? 
Is this the right forum to ask? There are several options in the official web. My apologies if this is not the right one.


Thanks so much for helping.
Welcome to blender.stackexchange. Please only post one question per post, you can post as many new questions as you want!


If you have the 3DView Transform Panel (N) open, it will show you the coordinates of a vertex. You can use an arithmethic operation if you want to offset a value. E.g. if the vertex is at (1, 2, 3) and you want to move it 4.5 units along Y, then you can simply double click into the Y field of the vertex transform. It will now read 2m followed by the cursor. Typing +4.5 and pressing &#9166; Enter will shift it to 6.5 as expected.

You can also use the operation properties which appears in the box after completing an operation. Press GY and confirm with  LMB to move the vertex along Y. The operation dialog will show




Move X       0m
     Y       0.12345m
     Z       0m


Now you can change the the relative value, by clicking on the individual field, entering it and confirming with &#9166; Enter or  LMB.



The BoolTools Addon is not yet updated for 2.8. (25.12.19)
In Object Mode (&#8633; Tab if you're in edit mode): Press &#9096; CtrlNumber to change the view level of the subdivision surface modifier. &#9096; Ctrl1 will be level one while &#9096; Ctrl0 will show no subdivision at all, etc...

The gizmo is enabled with the buttons on the left hand side T or with Space > G/R/S/3
Questions 1 - 4 are almost right for this forum, view the asking section for more info. They should however be split into several posts in the future. This question  may get closed for that reason. Question 5 however, does not have anything to do with the usage of Blender, but with the  usage of this forum. It belongs to meta.
