There is a feature I always missed in Texstudio, in the following context:
Someone is working in a given project, and program some macros, specially to replace commonly used symbols, which are hard to type (uC to turn into $\mu$C for example).
But the issue is that I have to program these macros on both my laptop and desktop. And everytime I format my computer, I have to reprogram all the macros, because of course one always forget to save the texstudio config files.
What if the macros were saved in the project working dir, so it could be synced (e.g. via dropbox), so that it would work in all the machines.
Also because macros are very context specific, and sometimes some old macros end up bothering you on new projects.
Another COOL feature would be tohave the possibility of adding visual shortcuts to the macros into the bookmarks on the left sidebar, with all the other shortcuts. Or maybe simply a new tab showing the macros of that project. That would help to visually remember the macros you have on that project, and re-use them more often.
I would gladly contribute if I can.
