Thank you for your post.
Beginning with FileMaker Go 13, when you enter Find Mode, no field will be active. You have to select it. Therefore, after Enter Find Mode, insert "Go to Field [ Select/perform ; SampleDB::name ]". This will then activate the field.
Even with that said, once you select the field, you still have to press Continue to get out of pause mode and execute the Find. Therefore, you may want to consider adding a OnObjectModify script trigger on the name field (only for Find mode), and have that execute Perform Find. That way, you will not need to press Continue.
Let me know if you need additional clarification.
My apologies. I forgot you asked two other questions.
2. The spacing may be a bit different. However, as I look at your button for Search, the "Search" text is not grouped with the actual button, so you may want to consider grouping them together so they stay in alignment. Although there were some early issues with River and River Touch themes, these should now be stable.
3. FileMaker Go 15 will not connect to FileMaker Pro 12. Please see the FileMaker Go Technical Specifications at:
1. I just put a quick sample.
2 & 3. I didn't group the sample. I plan on upgrading to 15 next month and rebuilding so I'll be ok with the other issues
