General ⇒ List of figures margin

[marbocam]

Is there a way to change the margin in my list of figures so that the numbering is more separated from the text?

e.g.: 2.1.12A 25GHz RoF transmission using developed TOSA with 16-QAM modulation
for dierent ber lengths with an additional 1.5m-long seamless antenna link.

12 and A should be more separated

This worked for me:

\usepackage{tocloft}
\setlength{\cftfignumwidth}{3em}
