I have all my projects classified by categories: work/personal/self-improvement etc.
It is really important for me to have all my projects grouped, so then I'm at work I don't have to chase all my work-related projects in a looong list.
In a previous version with project list auto-sort I used 1 digit prefix for each project type in a beginning of project's name. It worked just fine for me.
Now each time I create a new project I have to open project list and drag it to appropriate group. This is really annoying.

Proposal is: reintroduce automatic list sort as an optional feature.
Better solution: leave manual sort (which is useful), but let new projects add not to the end of a list, but into appropriate alphabetic position. Probably as optional feature as well.
In a perfect world it would be great to have project grouping by tag. As far as I understand tag in DOIT is supposed to match area of responsibility concept in GTD, so it is the most logical way. Grouping by goal or context could work fine as well.

PS. I know, that filters are workaround, but they are not powerful enough.

Thanks in advance!
