hi. I have two problems in devc++:

1. I have set the tabsize 2. but when submitting on codeforces the visible code is a disaster. tabsize 2 has changed and the code is ruined. How can I fix it?

2. I have built a library for famous algorithms/data structures but don't know how to insert the prewritten code fast. Does anybody know how to do that?

Thanks in advance for helping.
