In this work we use our state of the art IP-Glasma+MUSIC+UrQMD framework to systematically study a wide range of hadronic flow observables at 2.76 TeV and to make predictions at 5.02 TeV \cite{1609.02958}. In addition to the single particle spectra and anisotropic flow coefficients $v_n$, we study event-plane correlations, non-linear response coefficients $\chi_n$, and flow factorization breaking ratios $r_n$, which were presented for the first time in the IP-Glasma framework. Furthermore, we investigate event shape engineering as well higher flow harmonics such as $v_5$, $v_6$, and $v_7$, which were recently measured at 5.02 TeV by the ATLAS collaboration. Taken together, these observables provide a wealth of insight into the collective behavior of the QGP and initial state fluctuations. These quantities shed light on flow correlations in different $p_{T}$ ranges, flow at fixed system size but different initial geometries, as well as the non-linear hydrodynamic response to the initial state energy anisotropy. By synthesizing this information we can gain further insight into the transport properties of the QGP as well as the fluctuation spectrum of the initial state. Finally, we examine the effect of pre-equilibrium longitudinal flow, which has previously been neglected in phenomenological studies, such as the hadron and direct photon spectra and $v_n$.
