" could you please describe the steps that lead to this behavior in more detail?"
Yes I can 
I’ve found that its only happening when you use same objects second time. I mean when you apply align once like center to center in x axis, then try to to align keeping same selection but changing minimum in y then objects seams to forget last alignment in x… So it’s not big problem since it’s almost never used to align same objects 2 times in row… Then i found that sometimes when you chose align from 3d cursor, it jumps to object… but again rather not used option… I think that align from 3d cursor to something can be erased…
select by type can be made from outliner if something
great description, thanks. i’ve managed to replicate it - now it should be fixed (see OP for updated files).
when you select 3d cursor as current selection it should align itself to active object (according to settings in target).
once again thanks for great feedback 
sure but i rather use it for more elaborate scene browsing/object manipulation as it needs it’s own window area (now have it always opened costs a lot of screen space and to open it each time i need to select an object by type is rather clumsy). for simple filtered object selection i’ve got the need for something you can use within the 3d view directly.
Fantastic work with this! I don’t use max but I wanted to try it out anyway and you have done a great job.
The only thing I noticed is that it overwrites right click with the BMax menu, even if you just use the script and not the key presets etc.
Is that supposed to happen?
Wow, thank you so much for sharing this! I’m a long-time Max user, but I’ve switched to Blender at home. I just installed this and I can tell already that it’s really going to help me out. Thanks again!
Wow, what is this? 3DBlender?? haha, very good, but I’m very used to Blender’s work flow and i can’t go back to 3dsmax (Yes I was a heavily user of that extremely slow “thing”), nevertheless thanks for your contribution to the Blender community, cheers from Mexico
Thank you !
You did a lot of work on this.
yes it overrides the right-click by default, but you can turn it off (and on and off…and so on:)) with the ‘right-click menu toggle’ at the bottom of the panel.
Thanks again Ozzkar, this has become a major part of my blender interface now. Cant imagine not having it. I hope you dont stop with the improvements, if not with this then perhaps something else in the future. =)
They recently contracted two more developers to focus on the game asset pipeline. If you are interested in showing your support for or adding something you think is important, here is the list for it:
ozzkar you build some good tools.
As 3dsmax user I can only thank you!!!
Very good job!
Great great and great … again thanks … Love that addons in blender are also free not like for 3ds… Does anyone have problem that key shortcut in selecting align tool is not working? M for maximum is underlined but pressing m, c or other does not change target or current object form… I hope I’m not gonna be thought as align maniac… just like the way tool work
ozzkar, can I suggest to add the “bisect” mode as slice??
In 3dsmax we have SlicePlane and bisect tool is really similar…
For me it fits better than other methods or at least I think it should be added…
your mouse must be within the mode selection pop-up/drop-down, i think that’s the blender’s way of telling the window it has focus (?).
i’m really glad to read this
thanks for tip. this will take some time to go through but it looks interesting.
great info, i’ll definitely have a look at it. well, this is what i was talking about in OP - these days blender is so huge under the hood and some things are rather hidden.
just a question: which version are you using? i searched for ‘bisect’ and it seems like it was added 23-aug-13 whereas last release (2.68a - the version i’m using) has the release date of 24-jul-13. am i right that this tool is available only in latest svn builds?
@ozzkar
you’re right, only latest svn builds
the 2.68a official hasn’t got the bisect tool
thanks for info. i think i stay with 2.68a for awhile
Hi,ozzkar.
is that possible let user define the popup menu’s hotkey ?
I like the menu ,but I like blender’s right click select behavior too.
Thanks for this nice tool
