yes 730 do have show more tiles option(on/off) dont worry
well, replaced my 730 today. same problem is there with this phone also. purple tint and the edges of tiles goes purple while dragging the screen :| any fix? any 1?
Thanks for the confirmation about live tiles column options, very much relieved to hear this as i use two columns and was worried due to 735 users reporting no such option.
Regarding the purple tint in all phones issue, just use the phone dude, there will definitely be some sort of software update/patch released for this and apart from that you do have one year warranty. You can also try this 930 purple fix :

Oddly the 735 does not have this option. You can only have 3 columns, there is no option in start+theme.
Yup, it seems the 735 does not have 2 columns option in start+theme, confirmed by Daniel Rubino too. 730 and 735 do have some differences though like:
1. No wireless charging circuit and contacts in 730, so you can't use wireless charging shells like 735 which has the contacts near battery at the bottom.
2. Dual sim in 730 vs single sim in 735
3. Micro Sim cards in 730 vs nano sim in 735
4. EDIT: It seems even 730 does not have 2 columns option like 735 as confirmed by many 730 users. So, only 3 columns possible.
