Cannot link to another topic in another file is a fatal fault, as well as not 1 file 1 map.

hi

i am in medical field, suppose i use xmind to study 1000 drugs, and need to exchange with classmates.

A. currently it's NOT 1 map 1 file, it's forcing me to have 1 file, then 1000 sheets.

1. medicine is hard to study because everything is cross-inter-connected. suppose now i have another xmind map say disease.xmindmap that have another 1000 sheets related to disease. but now I can't connect a single drug to a single disease? In what way xmind helps? I am now using the most obvious competitor's software mm, it can easily did this. I have reported this problem to xmind almost TEN years ago, but ignored.

2. suppose my classmate wanna exchange each of our mindmap on panadol, do you think exchanging two files of panadol-me.map <-> panadol-classmate.map is easier, or  "export, exchange, import" is easier? can you do versioning easily with say beyond compare 4? Again, I can do this easily using the competitor's software mm.

As a chinese, i don't want to use canada/germany's mm. I want a cheaper alternative, i hope the company wont one day sanction on my country and me. xmind previously is open sourced (i think the regular version is, so the file format is open) and i prefer xmind over mm which people say mm is "even more microsoft than microsoft". and ofcause, mm wont have linux/android versions that can EDIT.

it's TEN years before i point out the stupidcity of 1 file many shxxts. i don't have too many TEN years to wait. (so among these years i have to use mm)

please, do some good.
