Removing Tabs with proper indentation

[iffee82]

Hello guys again



My next problem is (which might not actually be a problem) that I wrote my document without indentation. Now when was asked to introduce indents in my document, what I simply did was to introduce a tab at the start of every new paragraph. But I feel recently now that it might be the wrong way to do that.
Shall I remove all the tabs by backspacing or deleting them from every paragraph? and introduce indentation from Paragraph menu. OR leave it like that? What if any problems can arise later while formatting the paragaphs if I keep the tabs as they are?

regards
Irfan
