One thing we always thought would be useful in DBA was an asset list.  On this list, you would record assets, price paid, depreciation schedule, and price sold for.  This would help you in tracking depreciation, gains, and losses.  
 
Currently, we use an EXCEL spreadsheet, but it would be nice to have this accounting information standardized in one place.

It would be nice to have EVO track asset acquistions, but sometimes the description entered on the first line of the po is insufficient. One would need the ability to add to the description. (i.e. if purchasing enters the serial number on the first line of the po, the machine or asset description entered on the 2nd line does not appear in the GL-E).
 
Currently, one could use GL-E by asset account to obtain this info, but it would be nice to regroup or add to descriptions. i.e. sometimes we purchase machine accessories/add on features which I would like to be able to group together for that machine.
 
As far as depreciation goes, I don't think this is feasible. Unless you do depreciation by individual item within a fixed asset account, how do you expect EVO to track it by individual asset within a group? That's where Excel or other Asset software is really required.
Also, there are far too many tax laws that change the calculation methods and rates to make it feasible or applicable to one industry.
